Acing the Fundamentals of Radiology: An Online Series for Medical Students and Interns.

Purpose: The current undergraduate radiology education predominantly integrates radiology with other disciplines during preclerkship years and is often taught by nonradiologists. Early exposure to radiology and profound understanding of scientific fundamentals of imaging modalities and techniques are essential for a better understanding and interest in the specialty. Furthermore, the COVID-19 pandemic-related impact on in-person medical education aggravated the need for alternative virtual teaching initiatives to provide essential knowledge to medical students.

Not Every Low-Dose Is Low-Dose: Impact of Revising Low-Dose CT Protocol on Mean Effective Radiation Exposure.

According to the American Urological Association imaging guidelines, patients presenting with renal colic should undergo low-dose (LD) rather than standard-dose (SD) noncontrast CT. The aim of the present study was to assess how often physicians ordered LD CT scans and to calculate mean effective radiation exposure (ERE) from CT scans from dose length products, and determine mean cumulative ERE over 1-year follow-up period. After obtaining ethics approval, a retrospective chart review was conducted for patients with renal colic presenting to the emergency department between August 1, 2015 and July 31, 2016 (Phase I) and between April 1, 2019 and October 1, 2019 (Phase II).

Teaching Radiology to Medical Students in Canada; a Virtual, Integrative, Clinical Approach.

Purpose: To construct, apply, and evaluate a multidisciplinary approach in teaching radiology to Canadian medical students.

Methods: A multidisciplinary team of radiology and other disciplines experts designed an online 5-session course that was delivered to medical students. The topics of each session were clinical cases involving different systems.

Detectability of choledocholithiasis on CT: The effect of positive intraduodenal enteric contrast on portovenous contrast-enhanced studies.

Background/aim: To retrospectively assess the accuracy of intravenous (IV) contrast-enhanced multidetector CT (MDCT) in choledocholithiasis detectability, in the presence and absence of positive intraduodenal contrast.

Patients And Methods: Over a 3-year period, patients in whom endoscopic retrograde cholangiopancreatography (ERCP) was performed within a week from a portovenous (PV)-enhanced abdominal CT were identified. The final cohort consisted of 48 CT studies in which the entire common bile duct (CBD) length was visualized (19 males, 29 females; mean age, 68 years).

Imaging of Small Bowel Obstruction following Gastric Bypass Surgery for Morbid Obesity: A retrospective review.

Objectives: This study is a single institution retrospective evaluation of imaging findings of small bowel obstruction (SBO) after retrocolic antegastric Roux-en-Y gastric bypass surgery for morbid obesity.

Methods: The radiological database of 490 patients who underwent gastric bypass surgery for morbid obesity from January 2001-2005 at the Royal Victoria Hospital McGill University Health Center was searched for SBO complications related to the procedure. There were 22 cases of small bowel obstruction related to the procedure.

The role of abdominal radiography in the evaluation of the nontrauma emergency patient.

Purpose: To characterize the utility of abdominal radiography for nontrauma emergency patients in a single-institution setting.

Materials And Methods: Following approval from the Director of Professional Services, a retrospective review of radiography and of patient records was conducted for patients who presented to a nontrauma emergency department over a period of 6 months and who were imaged by using abdominal radiography. Only the first radiograph per patient was used for analysis.

Making the best use of radiological resources in Canada.

Diagnostic imaging plays a crucial frontline role in healthcare, providing the information some physicians need to make a diagnosis and determine a course of treatment for their patients. However, wait times for access to diagnostic imaging examinations continue to be long. This is due to a number of factors, including the expanding indications for CT and MRI and growing reliance on imaging studies, Canada's lag in purchasing new equipment, an American influence on the Canadian healthcare system and clinicians' requests for inappropriate examinations.

Empathy theory and practice: a survey of psychologists and counselors.

Psychologists and counselors completed a questionnaire devised by the authors to explore the relationships between their extent of endorsement of empathy definitions, their use and views of empathy, and their identification with theories of psychotherapy. Results from 565 respondents suggested that those who identified with humanistic/experiential and psychodynamic theories seemed to have similar views of how empathy is defined and viewed and reported that they use empathy more than those with other theoretical inclinations. These findings suggest that there is some consistency between theoretical identification and definition, as well as reported use and views of empathy.
