Article Type: Academic Research | First Published: November 27, 2020
Computed Tomography (CT) is an efficient and non-invasive method to obtain data about internal structures of the human body. CT scans contribute with the highest absorbed doses in population due X-ray beam attenuation and it has raised concern in radiosensitive tissues. Techniques for the optimization of CT scanning protocols in diagnostic services have been developing with the objective of decreasing the absorbed dose in patient, aiming image quality within acceptable parameters for diagnosis b...

Magnetic Resonance Imaging of Symptomatic Swimmer’s Shoulder
Jake T Stahnke, DO, Mari Schenk, MD and Kipling P Sharpe, MD
Article Type: Original Research | First Published: November 16, 2020
Eleven detailed magnetic resonance imaging scans of symptomatic shoulders of swimmers who had arthroscopically demonstrated labral dysplasia were obtained between 2011 and 2014. One experienced musculoskeletal radiologist and one orthopedic surgeon interpreted each scan, specifically focusing on the anteroinferior labrum (from 3 to 6 o’clock). Nine of the eleven images (axial cuts) showed a more rounded/blunted appearance with undefined features at the anterior inferior labrum. Nine of nine im...

Inferior vena cava (IVC) is a major abdominal vein responsible for the transportation of deoxygenated blood from the lower extremities and the abdomen through diaphragm to the superior vena cava and eventually to the right atrium. IVC is located to the right of the midline and is an important anatomic structure in cases of operations involving the right kidney. In this paper we present a rare case of left sided IVC in a patient diagnosed with renal cell cancer who underwent open left partial nep...

2019 novel coronavirus disease (COVID-19) is a type β corona virus that causes severe acute respiratory syndrome. It is highly infectious and has spread widely around the world. Due to the fact that COVID-19 shares similar characteristics with influenza A, it is difficult to differentiate COVID-19 from other respiratory viruses at an early stage. In this study, we report a case of a 24-year-old female patient who got co-infection with COVID-19 and influenza A H1N1 in China. The case suggests th...

Article Type: Case Report | First Published: September 30, 2020
Computed tomography colonography (CTC) is a new radiologic technique for examination of the colorectum. The search for, analysis and interpretation of extra-colonic findings (ECFs) are a matter of permanent debate and review, given the arguments for and against them. To assess the prevalence and type of extracolonic findings (ECFs) in a screening population undergoing computed tomography colonography (CTC) in Riyadh region. This retrospective study was conducted in Riyadh region. To achieve the ...

Article Type: Original Research | First Published: September 24, 2020
To determine the difference in craniocaudal dimension of an inspiratory CT scan minus an expiratory CT scan that constitutes an average expiratory effort to potentially exclude air trapping. This study obtained approval from the Institutional Review Board. The craniocaudal dimensions of inspiratory and expiratory chest CT scans of 83 patients were examined by an experienced radiologist (MS with 20 years of experience). The difference between the two measurements, called the Slice Level Differenc...

Dicom Image Anonymization and Transfer to Create a Diagnostic Radiology Teaching File
Brent Burbridge, MD, FRCPC
Article Type: Brief Report | First Published: September 18, 2020
The creation of a digital, Diagnostic Radiology, teaching file system is reliant upon a process for selecting, anonymizing, and exporting Digital Image and Communications in Medicine (DICOM) images from a clinical Picture, Archive, and Communication System (PACS) to the teaching file. A local version of the Medical Imaging Resource Center - Teaching File System (TFS) from the Radiology Society of North America (RSNA) was deployed to create teaching files. Philips, Intellispace PACS, was the sour...

50 patients who were diagnosed to have solid focal liver lesions on sonography during the period August 2017 to September 2019 at JSS Medical College and Hospital, Mysuru underwent Shear Wave Sonoelastography [SWE], following which patient underwent ultrasound guided FNAC for histological evaluation. Benign vs. malignant hepatic lesions could be differentiated using a cut off value of 25 kPa. The overall sensitivity & specificity of SWE was found to be 66% and 30% respectively as a standalone te...
