Digital Breast Tomosynthesis:Update on Technology, Evidence, and Clinical Practice

Published in Radiographics : a review publication of the Radiological Society of North America, Inc

Digital breast tomosynthesis (DBT) has been widely adopted in breast imaging in both screening and diagnostic settings. The benefits of DBT are well established. Compared with two-dimensional digital mammography (DM), DBT preferentially increases detection of invasive cancers without increased detection of in-situ cancers, maximizing identification...

Multimodality Imaging Approach to Ovarian Neoplasms with Pathologic Correlation.

Published in Radiographics : a review publication of the Radiological Society of North America, Inc

Ovarian neoplasms can be categorized on the basis of histopathologic features into epithelial surface cell tumors, germ cell tumors, sex cord-stromal tumors, and metastases. While their imaging appearance is often nonspecific, it closely parallels the gross pathologic appearance, and radiologic-pathologic correlation is helpful to aid in a deeper u...

Bosniak Classification of Cystic Renal Masses, Version 2019: A Pictorial Guide to Clinical Use.

Published in Radiographics : a review publication of the Radiological Society of North America, Inc

Cystic renal masses are commonly encountered in clinical practice. In 2019, the Bosniak classification of cystic renal masses, originally developed for CT, underwent a major revision to incorporate MRI and is referred to as the Bosniak Classification, version 2019. The proposed changes attempt to (a) define renal masses (ie, cystic tumors with less...

Radiologic Features of Type II and Type XI Collagenopathies.

Published in Radiographics : a review publication of the Radiological Society of North America, Inc

Type II collagen is a major component of the cartilage matrix. Pathogenic variants (ie, disease-causing aberrations) in the type II collagen gene (COL2A1) lead to an abnormal structure of type II collagen, causing a large group of skeletal dysplasias termed type II collagenopathies. Because type II collagen is also located in the vitreous body of t...

Infiltrative Renal Malignancies: Imaging Features, Prognostic Implications, and Mimics.

Published in Radiographics : a review publication of the Radiological Society of North America, Inc

Infiltrative renal malignancies are a subset of renal masses that are morphologically characterized by a poorly defined interface with the renal parenchyma. Infiltrative renal malignancies are less common but more aggressive than more typical renal malignancies and carry an overall worse prognosis. Although an infiltrative renal process often repre...

A Practical Approach to Diagnosis of Spinal Dysraphism.

Published in Radiographics : a review publication of the Radiological Society of North America, Inc

Spinal dysraphisms (SDs) are congenital malformations of the spinal cord, determined by derangement in the complex cascade of embryologic events involved in spinal development. They represent a heterogeneous group ranging from mild clinical manifestations-going unnoticed or being discovered at clinical examination-to a causal factor of life quality...

Multisystem Imaging Manifestations of COVID-19, Part 2: From Cardiac Complications to Pediatric Manifestations.

Published in Radiographics : a review publication of the Radiological Society of North America, Inc

Infection with severe acute respiratory syndrome coronavirus 2 results in coronavirus disease 2019 (COVID-19), which was declared an official pandemic by the World Health Organization on March 11, 2020. COVID-19 has been reported in most countries, and as of August 15, 2020, there have been over 21 million cases of COVID-19 reported worldwide, with...

Abbreviated MRI for Hepatocellular Carcinoma Screening and Surveillance.

Published in Radiographics : a review publication of the Radiological Society of North America, Inc

To detect potentially curable hepatocellular carcinoma (HCC), clinical practice guidelines recommend semiannual surveillance US of the liver in adult patients at risk for developing this malignancy, such as those with cirrhosis and some patients with chronic hepatitis B infection. However, cirrhosis and a large body habitus, both of which are incre...

Chest CT in COVID-19: What the Radiologist Needs to Know.

Published in Radiographics : a review publication of the Radiological Society of North America, Inc

Chest CT has a potential role in the diagnosis, detection of complications, and prognostication of coronavirus disease 2019 (COVID-19). Implementation of appropriate precautionary safety measures, chest CT protocol optimization, and a standardized reporting system based on the pulmonary findings in this disease will enhance the clinical utility of ...
