The research work has been dedicated for computer tomography and devoted to the analysis of computer tomography scans. Visual diagnostic methods are widely applied in medicine. Therefore incidental findings are more often. An incidental finding is any abnormality not related to the illness or causes that prompted the diagnostic imaging test. Abnormalities of the paranasal sinuses are frequently encountered as incidental findings during spiral computer tomography evaluation of head and cone beam computer tomography for dental purposes. The growing number of imaging techniques performed per patient causes an increase in the number of incidental findings. How these findings should be managed is far from settled.The aim of this study was to retrospectively analyze the occurrence and type of incidental abnormalities of paranasal sinuses detected by radiographic examinations in the Latvian population of adults.The research work includes retrospective data of three hundred patients. They underwent spiral computer tomography scan of the head referred for non-sinus pathologies in Pauls Stradins Clinical University Hospital in Latvia between February 2015 and October 2015.This is the first report describing incidental findings of paranasal sinuses, the types, the most frequently affected sinuses in Latvian population of adults and also associations between incidental findings and such factors as age, gender, season, septal deviation and enlarged inferior nasal turbinates.

Objectives: The use of cone-beam computed tomography (CBCT) is well-established in clinical practice. This study seeks to categorize and quantify the incidental finding (IF) rate on CBCT in patients with cleft lip and palate (CLP) prior to orthodontic or surgical treatment. Methods: This is systematic retrospective review of head and neck CBCTs in patients with nonsyndromic CLP taken between 2012 and 2019 at a single tertiary referral center. All assessments were performed independently by 4 observers (a head and neck radiologist and 3 orthodontists, including 2 fellowship-trained cleft-craniofacial orthodontists ). The images were divided into 9 anatomical areas and screened using serial axial slices and 3D reconstructions. The absolute number of IFs was reported for each area and statistical analysis was performed. Results: Incidental findings were found in 106 (95.5%) of the 111 patients. The most common sites were the maxilla (87.4%, principally dental anomalies), paranasal sinuses (46.8%, principally inflammatory opacification), and inner ear cavities (18.9%, principally inflammatory opacification). Eleven patients had skull malformations. Thirty-three patients had IFs in 1 anatomical area, 49 patients in 2 anatomical areas, 19 patients in 3 areas, and 5 patients presented with IFs in 4 of the 9 anatomical areas. Discussion: In patients with CLP, IFs on CBCT exam were present in the majority of cases. Most patients with IFs had them in multiple anatomical areas of the head and neck. The maxillary dental–alveolar complex was the most common area. Inflammatory changes in the inner ear cavities and paranasal sinuses were also common; however, cervical spine and skull abnormalities were also identified. Clinicians caring for patients with CLP should be aware of IFs, which may warrant further investigation and treatment.

Category: Orthopedic Radiology Introduction/Purpose: Radiographs are one of the most common and widely available diagnostic imaging techniques that are used to evaluate orthopedic conditions. However, incidental findings on imaging may be observed as well, some of which may be very serious and have significant heath as well as legal ramifications if missed. This study evaluates the number of clinically relevant incidental findings reported for orthopaedic radiographs ordered in an academic orthopedic multispecialty group over one year. Methods: A retrospective review was conducted of 13,948 eligible radiographs recorded at our institution over a 12-month period. Reports were categorized based on exam type. Incidental findings were first categorized as either concern for malignancy or non-malignancy. The possibly malignant findings were further subdivided into malignancies in Bone or Lung tissues. The non- malignant findings were categorized into the following groups: Benign Bone Disease, Gastrointestinal Pathology, Gynecologic Pathology, Incidental Fracture, Infection, Inflammation, Respiratory Pathology, Soft Tissue Mass, Urologic Pathology, Vascular Pathology or Other. Results: Of the 13,948 radiographs, 286 radiographs reported at least one incidental finding totaling to 287 (2.06%) incidental findings. The 3 studies with the highest rates of incidental findings were Leg Length Alignment films (3.94%), Spine (3.88%), and Pelvis & Hip (2.76%). The three categories with the lowest rates of incidental findings were Hand & Wrist (0.56%), Tibia/Fibula Foot & Ankle (0.84%), and Forearm & Elbow (1.13%). Over one-third of incidental findings concerned malignancy or metastases with 87 (30.1%) and 18 (6.23%) identified in bone tissue and lung tissue, respectively. Benign Bone Disease (24.9%), Gastrointestinal Pathology (6.57%), and Gynecologic Pathology (5.88%) were categories with the highest rates of non-malignant incidental findings. Follow-up was recommended for 122 (42.5%) incidental findings. Conclusion: This study describes the rates of incidental findings on orthopedic radiographs. Radiographs of midline structures are more likely to report an incidental finding as opposed to radiographs of distal extremities. The exception is leg alignment films because these image the entirety of the lower extremity and the pelvis and thus a far larger volume of the body. Over one-third of incidental findings concerned possible malignancy or metastases and therefore follow-up with focused imaging should be recommended if suspicious. This information will be particularly useful for orthopaedic surgeons who read their own radiographs without a radiologist formally reviewing the films.

The gallbladder volvulus is a rare condition. There have been around 500 cases described worldwide. It is virtually impossible to diagnose it clinically as symptoms are analogous to those of acute cholecystitis. Small proportion of gallbladder volvulus cases get accurately diagnosed preoperatively according to available literature. The imaging such as computer tomography plays a crucial role in diagnosing this condition. Laparoscopic cholecystectomy is considered to be a gold standard treatment for this condition. In our report we present a case of gallbladder volvulus which was successfully diagnosed by means of computer tomography scan

Background: Since fluoroscopy-guided interventional therapies grew significantly in recent years, exposure to ionizing radiation (IR) either for patient or medical staff became a critical issue. IR exposure varies according to the physicians’ experience, patients’ body mass index (BMI), imaging techniques and type of the procedure performed. The purpose of this study is to calculate the reference IR doses for fluoroscopy-guided epidural injections per procedure and BMI to provide reference doses for potential use in future dose reduction strategies. Methods: A retrospectively, evaluation of patients who received epidural steroid injections between January 2015 and December 2020 in a university hospital interventional pain management center, was performed. This observational study was conducted with patients aged  18 who underwent 3711 epidural injections including cervical interlaminar, lumbar interlaminar, lumbar transforaminal and caudal approaches. Provided IR doses for each patient were also divided by patients’ BMI to obtain dose per BMI. Results: The highest IR dose per procedure was found in caudal epidural injection with 0.218 mGy m2 and lowest dose was in cervical interlaminar epidural injection with 0.057 mGy m2. The IR dose per procedure was 0.123 mGy m2 for lumbar transforaminal and 0.191 mGy m2 for lumbar interlaminar epidural injection. Caudal epidural injection had also the highest IR dose per BMI which was 0.00749 and cervical interlaminar epidural injection had the lowest radiation dose per BMI which was 0.00214. Conclusions: We proposed reference IR dose levels of four approaches of epidural injections obtained from 3711 injections performed in a university hospital pain medicine clinic. BMI of patients were taken into account with the dose levels of injections given per BMI. Multicenter research with standardized techniques will assure more reliable reference levels which will guide pain physicians to self-assess their own levels of radiation exposure.

Detection of cancer at an early stage is one of the principal factors associated with successful treatment outcome. However, current diagnostic methods are not capable of making sensitive and robust cancer diagnosis. Nanotechnology based products exhibit unique physical, optical and electrical properties that can be useful in diagnosis. These nanotech-enabled diagnostic representatives have proved to be generally more capable and consistent; as they selectively accumulated in the tumor site due to their miniscule size. This article rotates around the conventional imaging techniques, the use of carbon based nanodots viz Carbon Quantum Dots (CQDs), Graphene Quantum Dots (GQDs), Nanodiamonds, Fullerene, and Carbon Nanotubes that have been synthesized in recent years, along with the discovery of a wide range of biomarkers to identify cancer at early stage. Early detection of cancer using nanoconstructs is anticipated to be a distinct reality in the coming years.

Soft-tissue sarcomas are malignant tumors that require good management within specialized centers. Our study aims to assess the benefit of handling these kinds of tumors using the Multidisciplinary Meeting (MDM) approach. The current paper details this approach through a prospective study that has lasted for 42 months in the HASSAN II University Hospital Center, Fez, Morocco. During this research work, 116 cases were selected with an average age of 53 years. In 95.7% of the cases, it was found that the lower limb was the most frequent tumor type (78.4%). Also, ninety-two (92) patients (79.3%) have had a prior biopsy. Ninety-nine (99) patients (85.3%) have received a magnetic resonance imaging scan (MRI) before surgery. Sixty-three (63) patients were operated on, including R0 resection used for 37 patients, R1 used for 21 patients, and R2 used for five patients. As a result, liposarcomas were the most frequent type (30.1%), followed by synovial sarcomas (14.6%), leiomyosarcomas (9.5%), ewing sarcoma (8.6), and undifferentiated pleomorphic sarcomas (7.7%). In addition, neoadjuvant chemotherapy was used for 36 patients. The other 22 patients received adjuvant chemotherapy and/or radiotherapy. The overall survival rate was 60.56 months, which proves a significant improvement, thanks to the multidisciplinary meeting approach. Conclusion. The conducted investigation has shown that using MDM for managing soft-tissue sarcomas of extremities improves the patients’ survival rate. Moreover, results have proven MDM might allow optimal treatment regarding less local recurrence and metastasis.

Cardiac tumors are a rare pathology, especially among infants. For a long time, they were identified only on the autopsy or as an incidental finding during cardiovascular interventions. However, with additional experience, improved methods of the echocardiography and wide-scale introduction of additional diagnostic methods, such as computed tomography (CT) and magnetic resonance imaging (MRI) into practice, it has become possible to establish a life-time and, recently, even a prenatal diagnosis of this pathology. The presented clinical case demonstrates the need to apply an integrated approach and potential of applying such diagnostic methods as echocardiography, MRI, multi-spiral CT and positron emission tomography/CT in children with cardiac tumors for the diagnostics of the severity of the cardio-vascular defects, determination of treatment tactics and prognosis of a therapy.
