Comparison of abbreviated and complete MRI protocols for treatment response assessment of colorectal liver metastases.

Objective: To compare abbreviated magnetic resonance imaging (MRI) to complete MRI for treatment response assessment of colorectal liver metastases.

Material And Methods: This retrospective study included consecutive patients with colorectal liver metastases between January 1, 2012, and December 3, 2021, who were undergoing chemotherapy and who had at least one follow-up gadoxetic-enhanced MRI. For each patient, two MRIs (baseline MRI and follow-up MRI) were randomly selected.

CT Surveillance for Local Recurrence After Pancreatic Cancer Resection: Evaluation of Imaging Findings From the SAR Disease-Focused Panel Consensus Statement.

A Society of Abdominal Radiology (SAR) Pancreatic Ductal Adenocarcinoma (PDAC) Disease-Focused Panel (DFP) consensus statement described findings suspicious for local recurrence (LR) on surveillance imaging after PDAC resection. The purpose of this study was to evaluate interreader agreement and predictive utility of potential imaging findings of LR on serial surveillance CT examinations after the Whipple procedure for PDAC, using the SAR PDAC DFP consensus statement. This retrospective study included 126 patients (mean age, 68.

Novel Association of the NOTCH Pathway Regulator MIB1 Gene With the Development of Bicuspid Aortic Valve.

Importance: Nonsyndromic bicuspid aortic valve (nsBAV) is the most common congenital heart valve malformation. BAV has a heritable component, yet only a few causative genes have been identified; understanding BAV genetics is a key point in developing personalized medicine.

Objective: To identify a new gene for nsBAV.

Is Bicuspid Aortic Valve Morphology Genetically Determined? A Family-Based Study.

Bicuspid aortic valve (BAV) is a common congenital heart disease, with a 10-fold higher prevalence in first-degree relatives. BAV has different phenotypes based on the morphology of cusp fusion. These phenotypes are associated with different clinical courses and prognoses.

Gallbladder Volvulus Presenting as Acute Appendicitis.

Gallbladder volvulus is a rarely reported and diagnosed condition. We present a case of an elderly female with right lower quadrant pain mimicking acute appendicitis without conclusive imaging; however, due to worsening serological laboratory findings and sepsis picture, an exploratory laparotomy was performed. A necrotic gallbladder was removed, diagnosing gallbladder volvulus.

Two Anomalies in One: A Rare Case of an Intrahepatic Gallbladder with a Cholecystogastric Fistula.

The gallbladder can be situated in a variety of anomalous positions. An intrahepatic gallbladder - the second most common ectopic location of the gallbladder - is one that is completely embedded within the liver parenchyma. Described in the literature as early as 1935, intrahepatic gallbladders predominantly result from a developmental anomaly but in some instances have been reported to be secondary to chronic inflammation.

Comparison of comfort and image quality with two endorectal coils in MRI of the prostate.

Purpose: To prospectively evaluate comfort and image quality of prostate MRI using two different endorectal (ER) coils.

Materials And Methods: Thirty consecutive patients were prospectively randomized to receive prostate MRI using either a prostate endocoil (PEC) or colorectal endocoil (CEC). Patients and operators were surveyed with regard to endocoil placement.

Late in-hospital pressure gradient measurements improve prediction of long-term outcome of alcohol septal ablation in hypertrophic cardiomyopathy.

Background: Left ventricular outflow gradient is associated with increased morbidity and mortality in hypertrophic cardiomyopathy. Alcohol septal ablation is the alternative to surgery in cases refractory to drug therapy. The implication of LVOG measured 1 week post-ASA for prediction of outcome is unknown.

Noncardiac implantable pacemakers and stimulators: current role and radiographic appearance.

Objective: The purpose of this pictorial essay is to familiarize radiologists with the clinical functioning, proper anatomic positioning, appearance on radiographs and CT scans, potential complications, and MRI safety issues of several implantable noncardiac pacemaker and stimulator devices.

Conclusions: The use of noncardiac pacemakers and stimulators is rapidly increasing because of the utility of these devices in the management of surgically and medically refractory conditions. Unlike cardiac pacemakers, electrical stimulators are MRI compatible under certain circumstances.
