Effect of Diet on Physiologic Bowel F-FDG Uptake.

Intestinal F-FDG uptake is variable in whole-body PET/CT. In cancer patients, particularly those suspected of relapse or metastasis, F-FDG absorption might interfere with scan interpretation. This study evaluated the effect of diet on intestinal F-FDG absorption.

The Role of Emergency Radiology in COVID-19: From Preparedness to Diagnosis [Formula: see text].

Emergency trauma radiology, although a relatively new subspecialty of radiology, plays a critical role in both the diagnosis/triage of acutely ill patients, but even more important in providing leadership and taking the lead in the preparedness of imaging departments in dealing with novel highly infectious communicable diseases and mass casualties. This has become even more apparent in dealing with COVID-19, the disease caused by the novel coronavirus SARS-CoV-2, first emerged in late 2019. We review the symptoms, epidemiology, and testing for this disease.

The Utility of PET/CT in Guiding Radiotherapy Reduction for Children With Hodgkin Lymphoma Treated With ABVD.

ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine) is standard upfront chemotherapy for adults diagnosed with Hodgkin lymphoma (HL), but positron emission tomography (PET)-based response data following ABVD is lacking for pediatrics. Among children who received ABVD for HL, we document interim and end of therapy PET-computed tomography (CT) response by Deauville criteria, and survival outcomes following a response-based reduction in involved field radiotherapy (IFRT). Children 18 years of age or below with HL treated with ABVD between 2006 and 2015 who had interim PET/CT scans after 2 cycles of chemotherapy were included.

Metformin Discontinuation prior to FDG PET/CT: A Randomized Controlled Study to Compare 24- and 48-hour Bowel Activity.

Purpose To investigate the relationship of 24- and 48-hour metformin discontinuation to bowel uptake of fluorine 18 fluorodeoxyglucose (FDG) on PET/CT scans. Materials and Methods Patients with diabetes who were treated with metformin and referred for FDG PET/CT were randomized to three equal groups based on duration of metformin discontinuation: 24 hours, 48 hours, and no discontinuation (control group). Two interpreters blinded to the study groups assessed FDG uptake in multiple segments of small and large bowel qualitatively and semiquantitatively by using maximum standardized uptake values (SUVs).

Production and Clinical Applications of Radiopharmaceuticals and Medical Radioisotopes in Iran.

During past 3 decades, nuclear medicine has flourished as vibrant and independent medical specialty in Iran. Since that time, more than 200 nuclear physicians have been trained and now practicing in nearly 158 centers throughout the country. In the same period, Tc-99m generators and variety of cold kits for conventional nuclear medicine were locally produced for the first time.

Nonsteroidal anti-inflammatory drugs (NSAIDs) and non-opioids for acute renal colic.

Background: Renal colic is acute pain caused by urinary stones. The prevalence of urinary stones is between 10% and 15% in the United States, making renal colic one of the common reasons for urgent urological care. The pain is usually severe and the first step in the management is adequate analgesia.

Low-dose MDCT findings of blunt hepatobiliary trauma.

This pictorial essay shows low-dose multi-detector computed tomography (MDCT) findings of blunt hepatobiliary trauma, and describes the indications and protocol for MDCT. Given the universal usage of MDCT in assessing the liver in blunt abdominal trauma, reduction of patient dose is essential. The new l0se MDCT protocol presented here can achieve up to 50% dose reduction while maintaining diagnostic image quality and thus facilitate dose sensitive patient management.

Peer-reviewed publications by CUA members: then and now.

Objective: The objective of this study was to assess the characteristics of publications by members of the Canadian Urological Association (CUA) over a 10-year period.

Methods: All publications by active CUA members during the periods January 1993-December 1994 and January 2003-December 2004 were reviewed.

Results: Of the 487 active members in 1993-1994, 130 (26.

Implementation of a new undergraduate radiology curriculum: experience at the University of British Columbia.

Objectives: The purpose of this study was to review and revise the undergraduate radiology curriculum at the University of British Columbia to improve radiology education to medical students and to meet the needs of a medical program with province-wide distribution.

Methods: We identified the radiology content of the curriculum from the Curriculum Management and Information Tool online database, from personal interviews with curriculum heads, and from published information. Undergraduates' and recent graduates' opinions were solicited by means of surveys.
