Background: There are approximately 2.1 million recreational surfers in the United States. However, little has been reported on surfing-related injuries and, to date, no study has utilized magnetic resonance imaging (MRI) to characterize injury patterns. Objective: To use MRI to perform a descriptive analysis of surfing injuries in patients who presented to an urban tertiary care musculoskeletal hospital. This was not a hypothesis-driven study. Study Design: Case series. Level of Evidence: Level 4. Methods: A retrospective review of the picture archiving and communication system as well as the electronic medical record was performed to identify patients with surfing-related injuries who presented to a tertiary care musculoskeletal hospital for treatment. The search included participants over a 10-year period who presented between January 1, 2009, and August 1, 2018. Descriptive data analyses were performed to determine frequency of body part injured, diagnosis, and operative versus nonoperative treatment. Results: The search yielded 109 patients with surfing-related injuries and MRIs. A total of 90 patients presented within 6 months of their surfing injury and were included in the final analysis. The median age was 36 years (range, 12-66 years). A majority of the patients included were male (74%; n = 67). Acute surfing injuries were diagnosed via imaging in 72% (n = 65) of patients. The joints injured most commonly were the shoulder (46%; n = 30) and the knee (28%; n = 18). Only 17% (n = 11) of acute surfing injuries required surgery, while 83% (n = 54) were treated nonoperatively. Conclusion: The most common surfing-related injuries occurred in the shoulder and knee. Clinical Relevance: This study helps characterize the risk of injury for surfers and informs healthcare providers on common surfing injuries.

Background: Autologous osteochondral mosaicplasty (ie, mosaicplasty) results in satisfactory clinical outcomes and reliable return to play for patients with large or unstable lesions due to osteochondritis dissecans (OCD) of the humeral capitellum. However, the association between the healing of the reconstructed cartilage and clinical outcomes remains unclear. Purpose: To evaluate the efficacy of mosaicplasty in teenage athletes through use of clinical scores and imaging. The secondary purpose was to compare the clinical outcomes with images of centrally and laterally located lesions. Study Design: Case series; Level of evidence, 4. Methods: This study analyzed 22 elbows (all male patients; mean age, 13.5 ± 1.2 years) with capitellar OCD managed with mosaicplasty. Patients were divided into 2 groups according to the location of the lesions: central (10 patients) and lateral (12 patients). Evaluation was performed through use of the clinical rating system of Timmerman and Andrews, plain radiographs, and magnetic resonance imaging (MRI; the cartilage repair monitoring system of Roberts). The mean follow-up period was 27.5 months (range, 24-48 months). Results: Lateral lesions were significantly larger than central lesions (147.1 ± 51.9 mm2 vs 95.5 ± 27.4 mm2, P = .01). No other significant differences were found between central and lateral lesions. Timmerman and Andrews scores for both central and lateral lesions improved significantly from 125.0 ± 30.1 points and 138.3 ± 34.5 points preoperatively to 193.5 ± 11.3 points and 186.7 ± 18.1 points, respectively, at final follow-up ( P < .0001, P < .0001). Radiography identified complete graft incorporation in all cases and the absence of severe osteoarthritic changes or displaced osteochondral fragments. In the lateral group, the radial head ratio at final follow-up (1.83 ± 0.23) was significantly larger than the preoperative findings (1.75 ± 0.14, P = .049). The quality of joint surface reconstruction was found to be acceptable for central and lateral lesions on MRI evaluation. Conclusion: Mosaicplasty resulted in satisfactory clinical outcomes and smooth cartilage surface integrity in teenage athletes with OCD on their return to competition-level sports activities irrespective of lesion location.

Objectives To determine the sensitivity and specificity of magnetic resonance imaging (MRI) for the detection of perineural spread (PNS) along the intratemporal facial nerve (ITFN) in patients with head and neck cancers. Study Design Case series with chart review. Setting Tertiary care center. Subjects and Methods We included 58 patients with head and neck malignancies who underwent sacrifice of the ITFN between August 1, 2002, and November 30, 2015. Demographics, preoperative facial nerve function, prior oncologic treatment, and timing between MRI and surgery were recorded. Histopathology slides and preoperative MRI were reviewed retrospectively by a neuropathologist and a neuroradiologist, respectively, both blinded to clinical data. The mastoid segment of the facial nerve (referred to as the descending facial nerve [DFN]) and stylomastoid foramen (SMF) were evaluated separately. A grading system was devised when radiographically assessing PNS along the DFN. Results Histopathologic evidence of PNS was found in 21 patients (36.2%). The sensitivity and specificity of MRI in detecting PNS to the DFN were 72.7% and 87.8%, respectively. MRI showed higher sensitivity but slightly lower specificity when evaluating the SMF (80% and 82.8%, respectively). Prior oncologic treatment did not affect the false-positive rate ( P = .7084). Sensitivity was 100% when MRI was performed within 2 weeks of surgery and was 62.5% to 73.3% when the interval was greater than 2 weeks. This finding was not statistically significant (SMF, P = .7076; DFN, P = .4143). Conclusion MRI shows fair to good sensitivity and good specificity when evaluating PNS to the ITFN.

Objective To describe the prenatal diagnosis of Galen vein aneurysm (GVA) based on ultrasonography and magnetic resonance imaging (MRI) in a series of cases, as well as its postnatal outcomes and follow-up until 4 years of age. Methods A retrospective longitudinal study was performed, analyzing a database comprising seven cases of prenatal diagnosis of GVA at two Brazilian institutions from February of 2000 to May of 2012. The following data were evaluated: gestational age at diagnosis, GVA dimensions on ultrasonography, associated fetal changes, findings on fetal echocardiography, gestational age at delivery, type of delivery, birth weight, Apgar score at the 1st and 5th minutes, neonatal outcomes, and survival with follow-up until 4 years of age. Results The mean gestational age ± standard deviation on the prenatal diagnosis of GVA based on ultrasonography was 25 ± 4.9 weeks. The mean length of GVA was 3.2 ± 0.4 cm. The mean gestational age at birth was 37.5 ± 0.7 weeks, and a cesarean section was performed in 85.7% of the cases (6/7). The mean birth weight was 3,070 ± 240.4 g. The total survival rate was 42.8% (4/7), with three neonatal deaths. Of the four survivors, three presented with normal neuropsychomotor development until 4 years of age and only one showed serious neurological sequelae. Ultrasonography and MRI showed similar findings for all seven cases. Conclusions Galen Vein Aneurysm is associated with a high neonatal death rate. Therefore, its prenatal diagnosis is essential for parent counseling and follow-up at tertiary care institutions.

Background Hamstring strains can be of 2 types with different injury mechanisms, 1 occurring during high-speed running and the other during stretching exercises. Hypothesis A stretching type of injury to the proximal rear thigh may involve specific muscle-tendon structures that could affect recovery time. Study Design Case series (prognosis); Level of evidence, 2. Methods Fifteen professional dancers with acute first-time hamstring strains were prospectively included in the study. All subjects were examined, clinically and with magnetic resonance imaging, on 4 occasions after injury: at day 2 to 4, 10, 21, and 42. The clinical follow-up period was 2 years. Results All dancers were injured during slow hip-flexion movements with extended knee and experienced relatively mild acute symptoms. All injuries were located proximally in the posterior thigh close to the ischial tuberosity. The injury involved the semimembranosus (87%), quadratus femoris (87%), and adductor magnus (33%). All injuries to the semimembranosus involved its proximal free tendon. There were no significant correlations between clinical or magnetic resonance imaging parameters and the time to return to preinjury level (median, 50 weeks; range, 30-76 weeks). Conclusion Stretching exercises can give rise to a specific type of strain injury to the posterior thigh. A precise history and careful palpation provide the clinician enough information to predict a prolonged time until return to preinjury level. One factor underlying prolonged recovery time could be the involvement of the free tendon of the semimembranosus muscle.

ABSTRACT Objective To clinically and radiologically evaluate patients who received meniscal suture using the outside-in technique, comparing magnetic resonance imaging (MRI), arthro-magnetic resonance imaging (arthro-MRI), and arthro-computed tomography (arthro-CT) to evaluate the healing of meniscal sutures. Methods We evaluated eight patients with an average follow-up of 15 months. The evaluation analyzed clinical parameters using the Lysholm and IKDC scores as well as MRI, arthro-MRI, and arthro-CT imaging. Results At the end of the follow-up period, mean Lysholm score was 89.5 and mean IKDC score was 78.6. In the MRI, signs of meniscal healing were observed in 50% of the cases. The arthro-MRI and arthro-CT showed signs of healing in 75% of cases. There was a positive correlation between arthro-MRI and arthro-CT results in all the cases studied (kappa correlation index=1). Conclusion Meniscal suture using the outside-in technique presented good or excellent results in 87.5% of our patients. The arthro-CT and arthro-MRI showed the same level of accuracy in detecting healing of the sutured region of the meniscus. Level of Evidence IV; Case series.

Submit Manuscript | http://medc rav eonline.co m Introduction Colorectal adenocarcinoma is the third most common malignant neoplasia and the third leading cause of death from cancer in men and women in the United States. Current data show that the incidence of colorectal adenocarcinoma is decreasing in developed countries but increasing in developing countries. 1 The 2018 estimates of the Bra - zilian National Cancer Institute (Instituto Nacional do Câncer–INCA) were 17,380 new cases in men and 18,980 in women, making col - orectal adenocarcinoma the third most common neoplasia in men and the second most common in women in Brazil. 2 In the past 15 years, rectal cancer management has evolved in several aspects. Specifical - ly, a better understanding of the natural history of the disease, more precise radiological staging, multimodal therapeutic intervention, refined surgical techniques, and more detailed histopathological re - ports may have positively influenced patient survival. In this context, multidisciplinary management of colorectal cancer plays an important role and requires the coordinated teamwork of colorectal surgeons, oncologists, radiologists, and radiotherapists. 3 Total mesorectal exci - sion is still the basis of treatment in rectal cancer. However, neoadju - vant therapy and more conservative practices have been adopted in cases of clinical/pathological responses to radiochemotherapy. 4 Ra - diological evaluation of the response is of paramount importance for the selection of patients eligible for alternative treatment strategies, including ‘watch-and-wait’. Diffusion-weighted imaging is already being used routinely in the evaluation of the pathological response of rectal tumour patients submitted to neoadjuvant therapy. Some re - searchers have tried to estimate the tumour regression grade (TRG) using magnetic resonance imaging, as has been described for post-ra - diochemotherapy pathological evaluation, thus rendering it a valuable instrument. Considering the good results obtained with multimodal therapy in extraperitoneal rectal cancer, the evaluation of the pathological re - sponse post-neoadjuvant therapy must be considered as a factor for safe indication, both for the conservative option, in which the organ is preserved, and for radical surgical resection, influencing the choice between sphincter-preserving surgery and abdominoperineal excision. A precise evaluation, by comparing the results of post-neoadjuvant therapy magnetic resonance imaging with those obtained from his - Int J Radiol Radiat Ther. 2018;5(4):254 ‒ 258. 254 © 2018 Oliveira et al.

The Impact

Background The COVID-19 pandemic led to a widespread socioeconomic shutdown, including medical facilities in many parts of the world. The purpose of this study was to assess the impact on neuroimaging utilisation at an academic medical centre in the United States caused by this shutdown. Methods Exam volumes from 1 February 2020 to 11 August 2020 were calculated based on patient location, including outpatient, inpatient and emergency, as well as modality type, including computed tomography and magnetic resonance imaging. 13 March 2020 was designated as the beginning of the shutdown period for the radiology department and 1 May 2020 was designated as the reopening date. The scan volumes during the pre-shutdown, shutdown and post-shutdown periods were compared using t-tests. Results Overall, neuroimaging scan volumes declined significantly by 41% during the shutdown period and returned to 98% of the pre-shutdown period levels after the shutdown, with an estimated 3231 missed scans. Outpatient scan volumes were more greatly affected than inpatient scan volumes, while emergency scan volumes declined the least during the shutdown. In addition, the magnetic resonance imaging scan volumes declined to a greater degree than the computed tomography scan volumes during the shutdown. Conclusion The shutdown from the COVID-19 pandemic had a substantial but transient impact on neuroimaging utilisation overall, with variable magnitude depending on patient location and modality type.

Abstract Background The aim of this study was to: (i) describe the abnormalities seen on brain imaging in a group of children with en coup de sabre (EDCS) with/without Parry-Romberg syndrome (PRS); and (ii) identify clinical predictors of brain imaging abnormalities. Methods This was a single centre (Great Ormond Street Hospital, London) retrospective case series of patients with ECDS/PRS seen from 2000 to 2018. We identified patients with cutaneous manifestations consistent with the clinical descriptions of ECDS/PRS. Presenting clinical, laboratory, and radiological brain findings are described. Results are expressed as medians and ranges or frequencies and percentages. Fisher’s exact test was used to identify clinical associations with magnetic resonance imaging (MRI) abnormalities. Results Fourteen patients were studied: 6 males and 8 females; median age 14 years (range 3–20). We observed neuroimaging abnormalities in 2/6 ECDS and 5/8 ECDS/PRS patients. White matter signal abnormality, dystrophic calcification, leptomeningeal enhancement, and sulcal crowding were the typical findings on brain imaging. A total of 50% of patients had no MRI abnormality despite some of these patients having neurological symptoms. The presence of seizures was significantly associated with ipsilateral enhanced white matter signalling on MRI (p < 0.05). Conclusions In summary, we observed several distinct radiographic patterns associated with ECDS/PRS. Seizure disorder was strongly associated with the presence of ipsilateral enhanced white matter signalling. Improved neuroimaging techniques that combine morphological with functional imaging may improve the detection rate of brain involvement in children with ECDS/PRS in the future.

Tertiary care centres continue to experience over-utilisation of diagnostic imaging services for lower back pain cases that may not be required. Moreover, these services may require additional time and consequently delay access to services that offer conservative management, i.e., physiotherapy, and hence, increase the direct and indirect costs with no added quality of care. A logic model was developed based on qualitative and quantitative studies that explains the plan and process evaluation strategies to reduce imaging for lower back pain in tertiary hospitals. Logic models are useful tools for defining programme components. The delivery of the components is ensured by well-defined process evaluations that identify any needed modifications. The proposed logic model provides a road map for spine clinics in tertiary care hospitals to decrease the number of patient referrals for magnetic resonance imaging and waiting times for consultations and services and promote early access to physiotherapy services.
