Diagnostic Accuracy of Ultrasound Guidance in Transthoracic Needle Biopsy: A Systematic Review and Meta-Analysis.

Purpose: To perform a systematic review and meta-analysis of relevant studies to assess the diagnostic accuracy and safety outcomes of ultrasound (US)-guided transthoracic needle biopsy (TTNB) for peripheral lung and pleural lesions.

Materials And Methods: A search was performed through Medline, Embase, Web of Science, and Cochrane Central from inception up to September 23, 2022 for diagnostic accuracy studies reporting US-guided TTNB (Prospero registration: CRD42021225168). The primary outcome was diagnostic accuracy, which was assessed by sensitivity, specificity, likelihood ratios (LR), and diagnostic odds ratio.

Risk of malignancy in T1-hyperintense Bosniak version 2019 class II and IIF cystic renal masses.

Background: Bosniak classification version 2019 includes cystic masses in class II and IIF based partly on their hyperintense appearance at T1-weighted MRI. The prevalence of malignancy in non-enhancing heterogeneously T1-hyperintense masses is unknown, nor whether the pattern of T1 hyperintensity affects malignancy likelihood.

Purpose: To determine the malignancy proportion among six patterns of T1 hyperintensity within non-enhancing cystic renal masses.

External Validation of a Five-Tiered CT Algorithm for the Diagnosis of Clear Cell Renal Cell Carcinoma: A Retrospective Five-Reader Study.

In 2022, a five-tiered CT algorithm was proposed for predicting whether a small (cT1a) solid renal mass represents clear cell renal cell carcinoma (ccRCC). The purpose of this external validation study was to evaluate the proposed CT algorithm for diagnosis of ccRCC among small solid renal masses. This retrospective study included 93 patients (median age, 62 years; 42 women, 51 men) with 97 small solid renal masses that were seen on corticomedullary phase contrast-enhanced CT performed between January 2012 and July 2022 and subsequently underwent surgical resection.

Tracking and predicting COVID-19 radiological trajectory on chest X-rays using deep learning.

Radiological findings on chest X-ray (CXR) have shown to be essential for the proper management of COVID-19 patients as the maximum severity over the course of the disease is closely linked to the outcome. As such, evaluation of future severity from current CXR would be highly desirable. We trained a repurposed deep learning algorithm on the CheXnet open dataset (224,316 chest X-ray images of 65,240 unique patients) to extract features that mapped to radiological labels.

Prophylactic retromuscular mesh placement for parastomal hernia prevention: a retrospective cohort study of permanent colostomies and ileostomies.

Purpose: Parastomal hernia (PSH) is the most common complication of stoma formation. The safety and efficiency of prophylactically placing mesh to prevent PSH remain controversial. To address this question, we examined the incidence of clinical and radiological PSH when using parastomal prophylactic mesh (PPM).

Ultrasound-guided transthoracic needle biopsy of the lung: sensitivity and safety variables.

Objectives: Variables affecting the performance of ultrasound-guided transthoracic needle biopsy (US-TTNB) are not well established. We examined clinical and imaging variables affecting the sensitivity and the complication rates of US-TTNB.

Methods: We retrospectively reviewed a consecutive series of 528 US-TTNBs performed from 2008 to 2017.

The role of radiological classification of parastomal hernia as a predictor of the need for surgical hernia repair: a retrospective cohort study.

Purpose: Parastomal hernia (PSH) is a frequent complication of stoma creation during colorectal surgery. Radiological classification systems have been proposed for PSH but are primarily used for research. Our objective was to determine if PSH radiological classification at diagnosis could predict the need for surgical repair during follow-up.

Effect of Yttrium-90 transarterial radioembolization in patients with non-surgical hepatocellular carcinoma: A systematic review and meta-analysis.

Background: Recently, the use of Yttrium-90 transarterial radioembolization in non-surgical hepatocellular carcinoma was suggested but the evidence supporting its use is unclear.

Methods: We searched Medline, Embase, Web of Science and Cochrane CENTRAL from inception up to April 14, 2020 for randomized controlled trials comparing Y90-TARE to standard of care in non-surgical HCC patients. Our primary outcome was overall survival (OS).

Management of retroperitoneal hemorrhage compressing the inferior vena cava in a patient with a renal transplant: A case report.

We report a case of a right retroperitoneal hematoma compressing the inferior vena cava (IVC) in a patient with a left pelvic renal transplant. Noncontrast abdominal computed tomography scan diagnosed the cause of the hematoma, which was a ruptured nontraumatic renal cyst hemorrhage from the right native kidney. The patient had been anticoagulated for 5 days to treat pulmonary embolism upon clinical presentation.
