Diagnostic performance of multiparametric MRI based Vesical Imaging-Reporting and Data System (VI-RADS) scoring in discriminating between non-muscle invasive and muscle invasive bladder cancer.

Purpose: The purpose of the present study was to assess the diagnostic accuracy of the Vesical Imaging-Reporting and Data System (VI-RADS) scoring system in predicting muscle infiltration of bladder cancer (BC) on a pre-operative multiparametric magnetic resonance imaging (mpMRI).

Methods: The prospective study enrolled patients with bladder lesions detected on a preliminary ultrasonography or cystoscopy. The patients underwent mpMRI on a 3T MRI scanner followed by surgery within 2 weeks.

Novel pulmonary vascular imaging signs in COVID-19: pathophysiology, significance and management.

A growing body of evidence points to the frequent involvement of pulmonary microvessels in COVID-19 which was recognized first on CT, and subsequently demonstrated by clinical and pathological studies. Microvasculopathy occurring chiefly from endothelial and pericyte damage with resultant disruption of immune, thrombotic and renin-angiotensin-aldosterone balance leads to a constellation of clinical and biochemical derangements. Exploration of potential therapies directed at normalizing the vascular health can prove a major boon in the treatment of COVID-19.

Clinicoradiological course in coronavirus disease-19 (COVID-19) patients who are asymptomatic at admission.

Objective: The study aimed to describe the clinical and imaging course of reverse transcriptase polymerase chain reaction) confirmed coronavirus disease (COVID-19) patients who are asymptomatic at admission.

Methods: This was a retrospective observational study. Severe acute respiratory syndrome coronavisrus-2 (SARS-CoV-2) positive cases that were asymptomatic at admission were retrospectively enrolled.

Chest CT features of coronavirus disease-19 (COVID-19) pneumonia: which findings on initial CT can predict an adverse short-term outcome?

Objective: To study the spectrum of chest CT features in coronavirus disease-19 (COVID-19) pneumonia and to identify the initial CT findings that may have the potential to predict a poor short-term outcome.

Methods: This was a retrospective study comprising 211 reverse transcriptase-polymerase chain reaction (RT-PCR) positive patients who had undergone non-contrast chest CT. Prevalence, extent, pattern, distribution and type of abnormal lung findings were recorded.

Spectrum of chest computed tomographic (CT) findings in coronavirus disease-19 (COVID-19) patients in India.

Purpose: To report the spectrum of chest computed tomographic (CT) imaging findings in coronavirus disease-19 (COVID-19) infected Indian patients.

Methods: This was a prospective descriptive study comprising 147 consecutive reverse transcriptase polymerase chain reaction (RT-PCR) positive patients who underwent CT chest. Prevalence, distribution, extent and type of abnormal lung findings were recorded.

Demystifying pulmonary vascular complications in severe coronavirus disease-19 pneumonia (COVID-19) in the light of clinico-radiologic-pathologic correlation.

• Small pulmonary vessel changes are a unique imaging feature of COVID-19 pneumonia. • Autopsy studies reveal a very high incidence of peripheral pulmonary thrombosis. • Risk of thrombosis is high in severe COVID-19 despite anticoagulation.

Preoperative Staging of Gastric Cancer Using Computed Tomography and Its Correlation with Histopathology with Emphasis on Multi-planar Reformations and Virtual Gastroscopy.

Background: Gastric cancer is the fifth most common cancer in the world. Preoperative staging of gastric cancer has assumed pivotal role in deciding appropriate management of gastric cancer with multi-detector computed tomography (MDCT) using hydro- and gaseous distension of stomach superseding endoscopic ultrasound in tumor (T) and nodal (N) staging. We undertook this study to evaluate the diagnostic accuracy of MDCT in the T and N staging of gastric cancer with an attempt to differentiate between early and advanced gastric carcinomas.

Cerebrotendinous xanthomatosis - A case report.

Cerebrotendinous xanthomatosis (CTX) is a rare autosomal recessive disorder resulting from a defective enzyme in bile acid synthesis pathway leading to neurological, ocular, vascular, and musculoskeletal symptoms from deposition of cholestanol and cholesterol in these tissues. We present clinical and imaging features of a 32-year-old female who presented with mental retardation, gait instability and swelling along posterior aspect of both ankles. Imaging studies were performed which revealed spectrum of CTX findings in brain and tendons.

Renal hydatid cyst presenting as an intrarenal-pelvic mass.

Intra-renal-pelvic hydatid cyst is a rare manifestation of renal hydatid disease, as most of the renal hydatid cysts are based in the renal cortex. We present and discuss the clinical and radiological findings of a 55-year-old woman who presented with left flank pain, frequency, dysuria, and hydatiduria. She was thoroughly investigated radiologically, and the diagnosis of intra-renal-pelvic hydatid cyst was confirmed surgically.

Recurrent Unexplained Cystitis Due to an Ingested Foreign Body-An Extremely Rare Case.

We present the images of a 4-year-old male child with history of recurrent unexplained urinary tract infections which was found to be due to an ingested wooden foreign body which had perforated the small bowel into the posterior bladder wall. Such cases are very rare, usually due to domestic abuse or in patients with psychiatric illnesses. The adults usually report early but in children these cases go un-noticed.

Evaluation of intracranial tuberculomas using diffusion-weighted imaging (DWI), magnetic resonance spectroscopy (MRS) and susceptibility weighted imaging (SWI).

Objective:: The present study was aimed to evaluate patients of suspected intracranial tuberculomas with diffusion-weighted imaging (DWI), magnetic resonance spectroscopy (MRS) and susceptibility-weighted imaging (SWI).

Methods:: The present study evaluated 116 patients known or suspected of having central nervous system tuberculosis with advanced MRI techniques comprising of DWI, MRS and SWI in addition to the conventional MRI.

Results:: Apparent diffusion coefficient value of tuberculomas was not significantly different (p > 0.
