Review of Extraskeletal Activity on Tc-99m Methylene Diphosphonate Bone Scintigraphy and Value of Cross-Sectional and SPECT-CT Imaging Correlation
Recognizing the different mechanisms and imaging appearance of extraskeletal Tc-99m methylene diphosphonate uptake enhances the diagnostic value of bone scan interpretation. In this article, we present a pictorial review of the different mechanisms of extraskeletal Tc-99m methylene diphosphonate uptake on bone scintigraphy including neoplastic, inflammatory, ischemic, traumatic, excretory, and iatrogenic. We also illustrate through case examples the added value of correlation with cross-sectional and single photon emission computed tomography and computed tomography imaging in localizing and characterizing challenging case...

Computed Tomography –Detected Paleopathologies in Ancient Egyptian Mummies
Computed tomography (CT) –based analyses of mummies have been performed since the 1970s but, until now, no systematic summary of PubMed®-published data has been performed. The aim was to perform a systematic review of previously published cases and summarize artificial changes and detectable paleopathologies. (Source: Current Problems in Diagnostic Radiology)

Radiology Trainee vs Faculty Radiologist Fluoroscopy Time for Imaging-Guided Procedures: A Retrospective Study of 17,966 Reports Over a 5.5-Year Period
To evaluate differences in fluoroscopy time (FT) for common vascular access and gastrointestinal procedures performed by radiology trainees vs faculty radiologists. Report information was extracted for all 17,966 index fluoroscopy services performed by trainees or faculty, or both from 2 university hospitals over 66 months. Various vascular access procedures (eg, peripherally inserted central catheters [PICCs] and ports) and gastrointestinal fluoroscopy procedures (eg, upper gastrointestinal and contrast enema studies) were specifically targeted.

Pediatric Skeletal Scintigraphy: What a General Radiologist Needs to Know
Pediatric skeletal scintigraphy is a noninvasive imaging modality which aids in functional as well as anatomic evaluation of bone. Bone scintigraphy plays a major role in diagnosis and evaluation of various benign, primary malignant and metastatic pediatric bone pathologies. The advantage of bone scan is that it becomes positive well before the bone pathology is evident on radiographs and specifically the entire skeleton can be imaged in a single examination. Pediatric bone scintigraphy evaluation can be challenging to the general radiologist not routinely exposed to the study, as the growing skeleton is quite different fr...

Current Techniques and Clinical Applications of Computed Tomography Urography
From conventional radiograph to magnetic resonance urography, imaging of urinary system has evolved with variety of investigations over the past several decades with each of them having advantages and limitations of their own. In the current era, computed tomography (CT) has emerged as a preferred investigations for evaluation of the urinary tract. There are various techniques involved in performing CT urography (CTU) with triple bolus technique (TB-CTU) currently drawing a special attention because of its low radiation exposure.

Altmetrics: A Measure of Social Attention Toward Scientific Research
The quality and effect of scientific research is traditionally measured by citation-based metrics. However, the internet and social media revolution has led to radical changes in the way scientific information is shared and how it affects the world. Alternative metrics (altmetrics) is a rapidly evolving measure to quantify social media attention received by a scientific work. It is a complement to the conventional metrics and has tremendous potential in enabling faster alternative ways of evaluating research impact. (Source: Current Problems in Diagnostic Radiology)

Let ’s Make Academic Radiology Great Again
Today ’s skeptics may paint a very gloomy picture of academic radiology. These issues are echoing throughout North America: clinical workload is insane, reimbursement is plummeting, 24/7/365 coverage is destroying the work-life balance, and artificial intelligence will soon make us jobless. The pessimis ts should hold off to fold our tent and instead seriously consider the ways to continue to attract the best and the brightest to our specialty.
