Aided Diagnosis

BACKGROUND Computer-aided diagnosis (CAD) is a useful tool that can provide a reference for the differential diagnosis of benign and malignant breast lesion. Previous studies have demonstrated that CAD can improve the diagnostic performance. However, conventional ultrasound (US) combined with CAD were used to adjust the classification of category 4 lesions has been few assessed. OBJECTIVE The objective of our study was to evaluate the diagnosis performance of conventional ultrasound combined with a CAD system S-Detect in the category of BI-RADS 4 breast lesions. METHODS Between December 2018 and May 2020, we enrolled patients in this study who received conventional ultrasound and S-Detect before US-guided biopsy or surgical excision. The diagnostic performance was compared between US findings only and the combined use of US findings with S-Detect, which were correlated with pathology results. RESULTS A total of 98 patients (mean age 51.06 ±16.25 years, range 22-81) with 110 breast masses (mean size1.97±1.38cm, range0.6-8.5) were included in this study. Of the 110 breast masses, 64/110 (58.18%) were benign, 46/110 (41.82%) were malignant. Compared with conventional ultrasound, a significant increase in specificity (0% to 53.12%, P<.001), accuracy (41.81% to70.19%, P<.001) were noted, with no statistically significant decrease on sensitivity(100% to 95.65% ,P=.48). According to S-Detect-guided US BI-RADS re-classification, 30 out of 110 (27.27%) breast lesions underwent a correct change in clinical management, 74of 110 (67.27%) breast lesions underwent no change and 6 of 110 (5.45%) breast lesions underwent an incorrect change in clinical management. The biopsy rate decreased from 100% to 67.27 % (P<.001).Benign masses among subcategory 4a had higher rates of possibly benign assessment on S-Detect for the US only (60% to 0%, P<.001). CONCLUSIONS S-Detect can be used as an additional diagnostic tool to improve the specificity and accuracy in clinical practice. S-Detect have the potential to be used in downgrading benign masses misclassified as BI-RADS category 4 on US by radiologist, and may reduce unnecessary breast biopsy. CLINICALTRIAL none

Abstract Introduction Point-of-Care Ultrasound (POCUS) has been shown to be a useful adjunct in assessment of various shock states and utilized to guide resuscitative and post-resuscitation de-escalation efforts. POCUS use for guiding resuscitation in burn injured patient has not be described. Objectives characterize the use of bedside ultrasound examinations performed by advance practice providers and treating physicians in a regional burn intensive care unit Methods Daily beside ultrasound examinations were performed utilizing a bedside ultrasound device by an advanced practice provider prior to rounds POCUS examinations consist of: Ultrasound images were archived to a centralized image repository and reviewed daily during multi-disciplinary rounds. Ultrasonographic volume assessment compared to clinical volume assessment made during daily multidisciplinary rounds. Results 100 examinations were performed of those 32 were within the initial 72 hour window: Conclusions Our results demonstrate that bedside ultrasound aides in guidance of both resuscitative and post-resuscitative efforts. We identified a cohort of patients who appeared hypervolemic clinically but US findings supported hypovolemia, we refer to as pseudohypervolemia US volume assessment provides information that changes management. We believe point of care ultrasound is a viable tool in preventing over-resuscitation as well as to guide post-resuscitative diuresis.

Abstract Background Liver cirrhosis is a multi-etiological entity that alters the hepatic functions and vascularity by varying grades. Hereby, a cross-sectional study enrolling 100 cirrhotic patients (51 males and 49 females), who were diagnosed clinically and assessed by model for end-stage liver disease (MELD) score, then correlated to the hepatic Doppler parameters and ultrasound (US) findings of hepatic decompensation like ascites and splenomegaly. Results By Doppler and US, splenomegaly was evident in 49% of patients, while ascites was present in 44% of them. Increased hepatic artery velocity (HAV) was found in70% of cases, while 59% showed reduced portal vein velocity (PVV). There was a statistically significant correlation between HAV and MELD score (ρ = 0.000), but no significant correlation with either hepatic artery resistivity index (HARI) (ρ = 0.675) or PVV (ρ =0.266). Moreover, HAV had been correlated to splenomegaly (ρ = 0.000), whereas HARI (ρ = 0.137) and PVV (ρ = 0.241) did not significantly correlate. Also, ascites had correlated significantly to MELD score and HAV (ρ = 0.000), but neither HARI (ρ = 0.607) nor PVV (ρ = 0.143) was significantly correlated. Our results showed that HAV > 145 cm/s could confidently predict a high MELD score with 62.50% and 97.62 % sensitivity and specificity. Conclusion Doppler parameters of hepatic vessels (specifically HAV) in addition to the US findings of hepatic decompensation proved to be a non-invasive and cost-effective imaging tool for severity assessment in cirrhotic patients (scored by MELD); they could be used as additional prognostic parameters for improving the available treatment options and outcomes.

Specific Symptoms

Background:Giant cell arteritis (GCA) has two subtypes, the cranial form (“cranial GCA”) and the large-vessel form (“LV-GCA”). GCA can present with “cranial” symptoms (headache, visual symptoms, jaw claudication, scalp tenderness), constitutional symptoms (fever, fatigue), limb claudication and symptoms of polymyalgia rheumatica (PMR) and usually causes increased inflammation markers, anemia and thrombocytosis. Ultrasound (US) of the temporal and axillary arteries has a well-established role in cranial GCA and LV-GCA diagnosis, respectively. However, it is unknown whether specific clinical and laboratory parameters are linked with US findings suggestive of vascular inflammation (“halo” sign).Objectives:The aim of this study was to examine possible association between clinical and laboratory characteristics of the patients and detection of vessel wall inflammation in the US.Methods:Patients ≥50 years old with elevated ESR (≥50mm/h) and/or CRP (≥10mg/L) that presented in our outpatient rheumatology clinics from July 2017 to December 2019 with possible clinical diagnosis of GCA were included. Three groups were compared: Patients with “cranial symptoms” (with or without PMR), patients with PMR symptoms only and patients with increased inflammation markers without specific symptoms indicative of GCA. Temporal arteries and their main branches, as well as facial and axillary arteries were evaluated by US bilaterally for the presence of non-compressible “halo sign” at the vessel wall. Clinical symptomatology and the occurrence of anemia and thrombocytosis were recorded.Results:52 patients were included. 71.2% were females, with a mean±SD age of 71.0±10.0 years. 17 patients had “cranial symptoms” (seven patients with concomitant PMR and ten without), 17 patients had PMR symptoms only, while 18 patients had non-specific symptoms (e.g. fever) (Table 1). Among 17 patients with “cranial symptoms”, 7/7 (100%) with concomitant PMR had a positive temporal US, while only 3 out of 10 (30%) without PMR had a positive temporal US (p<0.01) and US was indeterminate in 2 of them (20%). Collectively, 10/17 (58.8%) of patients with “cranial symptoms” and systemic inflammation had a US examination compatible with GCA. No patient with “cranial symptoms” had a positive US of axillary arteries. No patient with only PMR symptoms, had “halo sign” in temporal and facial arteries, while 3 out of 17 (17.6%) had a positive axillary US. From the 18 patients with elevated ESR/CRP, one had a positive temporal US and another one had a positive axillary US. Regarding specific symptoms, positive temporal US was associated with new headache (p=0.003), vision impairment (p=0.001), jaw claudication (p=0.05), scalp tenderness (p=0.01) and fever (P=0.002), but not with PMR (p=0.317). Thrombocytosis was associated with an increased risk for “halo sign” detection in temporal (p=0.04) and facial (p=0.007) arteries, but not in axilliary arteries (p=0.52).Conclusion:60% of patients with “cranial symptoms” and elevated inflammation markers have US temporal findings indicative of GCA. This is more pronounced in patients with concomitant PMR symptoms and is associated with specific symptomatology. 18% of patients with only PMR symptoms might have LV-GCA, while those with high ESR/CRP without GCA-related symptoms rarely have “halo sign” in US.Disclosure of Interests:None declared

Background:In rheumatoid arthritis (RA), biologics treatment is one of the effective treatment options. Usually, there is no difference in therapeutic effect regardless of which biologics is used, but the effect for joint synovitis is unknown. Recently, ultrasound (US) has played a role of sensitive imaging modality in the diagnosis and follow-up of patients with RA.Objectives:The aim of this study was to compare the improvement of US findings between TNF inhibitors and non-TNF inhibitors at first biologics in patients with RA.Methods:Fifty-four RA patients who started the first biologics from September 2016 to December 2018 were included in this longitudinal study (SPEEDY study, UMIN000028260). All the patients were performed clinical examination, blood test and US examination at baseline, 4, 12, 24, 36 and 52 weeks. A US examination was performed at the bilateral first to fifth metacarpophalangeal (MCP) joints, first interphalangeal (IP) and second to fifth proximal interphalangeal (PIP) joints, wrist joints (three part of radial, medial and ulnar) and first to fifth metatarsophalangeal (MTP) joints, by using HI VISION Ascendus (Hitachi Medical Corporation, Japan) with a multifrequency linear transducer (18-6 MHz). The gray scale (GS) and power Doppler (PD) findings were assessed by the semi-quantitative method (0-3). GS score and PD score (both 0-108 points) were defined as the sum of each score. The change of disease activity and US findings were compared between TNF group and non-TNF group.Results:Among 54 cases, 32 patients were used TNF inhibitor and 22 were non-TNF inhibitor. Age and duration of RA were significantly higher in the non-TNF group, and MTX dose was significantly lower in the non-TNF group. The baseline inflammatory markers tended to be higher in the non-TNF group and the disease activity was also higher in the non-TNF group. However, the US findings showed no significant difference in both GS and PD between two groups at baseline. US improvement ratio was no difference between TNF group and non-TNF group at 4, 12, 24, 36 and 52 weeks in both GS and PD score. Regardless of the type of biologics, patients with long-term disease duration tended to have poor improvement in US synovial fingings.Table 1.Baseline patient and disease characteristicsTNF (n=32)non-TNF (n=22)P valueFemale patients, n (%)21 (65.6)16 (72.7)0.767Age (years)63.5±15.471.0±9.00.030Disease duration (years)6.5±8.213.0±11.70.032CRP (mg/dl)1.8±2.53.0±3.20.170DAS28-ESR5.0±1.45.8±1.20.022GS score26.1±18.831.8±21.10.313PD score17.6±11.423.1±14.60.150Figure 1.GS and PD improvement ratio at 4, 12, 24, 36 and 52 weeksConclusion:There was no difference in the US findings improvement between patients with TNF inhibitor and non-TNF inhibitor at first biologics in patients with RA.References:[1]Grassi W, Okano T, Di Geso L, Filippucci E.

OBJECTIVE: To assess iliac blood vessels using conventional ultrasound (US) and contrast-enhanced ultrasonography (CEUS) before kidney transplantation (KT) and determine whether US findings related to post-transplant outcomes. METHODS: A total of 119 patients received US and CEUS before KT waiting-list acceptance. The preoperative iliac blood hemodynamics and vascular conditions were evaluated. The operative strategy and follow-up outcomes were recorded. Logistic regression and correlation analysis were used. The accuracy in determining the patency of iliac blood vessels was calculated before and after the injection of contrast materials. RESULTS: CEUS can help to significantly improve the visualization of the internal iliac artery, but there was no significant correlation with post-transplant outcomes. In terms of accuracy, there were significant differences in determining the patency of internal iliac arteries between conventional US and CEUS (60.5% and 100%, p <  0.001). The surgical strategy of one patient was regulated and two patients were excluded from KT according to US findings. CONCLUSIONS: Compared with conventional US, CEUS helps to improve the visualization of the internal iliac artery. Conventional US and CEUS have the potential to serve as effective methods to evaluate anatomy and hemodynamics of iliac vessels and have a potential value while defining clinical algorithms in surgery decision-making.
