A New CT Perfusion Analysis Algorithm without Deconvolution: FiTT

Hiroshi Iimura and Atsushi Senoo

Article Type: Original Article | First Published: September 30, 2021

We propose a new CT perfusion analysis algorithm without deconvolution: Theoretically calculating the time-enhancement curve (TEC) under various perfusion conditions, finding a theoretical TEC that best fits the observed TEC, and using the theoretical TEC’s perfusion parameters as the estimations for the observation point (FiTT). The FiTT analysis procedure was as follows: First, the TEC of the arterial input function (AIF) was fitted to the gamma distribution function. Next, we defined the re...

Assessment of Chest X-Ray Utilization for the Evaluation of Non-Traumatic Chest Pain in an Academic Emergency Department

Garrett Rucker, Ricci Kalayanamitra, MD and Ravindra Gopaul, MD

Article Type: Original Research | First Published: June 30, 2021

Overutilization of chest X-rays (CXR) is costly, inefficient and results in increased radiation exposure. Several studies have proposed clinical decision rules (CDR) for chest X-ray utilization in non-traumatic chest pain patients presenting to the Emergency Department (ED). However, CDRs are often not one size fits all and may differ based on population variability. The purpose of this study is to 1) Evaluate CXR utilization among ED patients suspected of acute coronary syndrome (ACS) presentin...

Agreement between Arthroscopy and Saline Magnetic Resonance Shoulder Arthrography in Adolescent Patients - Evaluation of Location and Extent of Injury of Labral Tears

Michael Fadell, MD, David Howell, Jill Stein, Marty McGraw, Alexia Gagliardi, Stephanie Pearce and Jay Albright

Article Type: Original Research | First Published: April 08, 2021

To compare potential differences in size and extent of labral tears on magnetic resonance arthrography of the shoulder performed with saline to shoulder to arthroscopy as the gold standard in adolescent patients with tears of the glenoid labrum. Pre-operative saline magnetic resonance arthrograms of the glenoid labrum were assessed by two radiologists for location and extent of the labral tear based on the clock-face method of visualization. The radiology findings were compared to the surgeon’...

The Most Accurate Ultrasonographic Finding for Diagnosis of Lower-Extremity Arterial Disease in Patients with Critical Limb Ischemia

Tanapong Panpikoon, Jiemjit Tapaneeyakorn, Tharintorn Treesit and Chinnarat Bua-ngam

Article Type: Original Article | First Published: March 13, 2021

To search for the most accurate duplex ultrasound finding for diagnosis of arterial stenosis and occlusion in patients with critical limb ischemia. Combining the findings from B-mode with color and spectral PW Doppler ultrasound showed the higher accuracy than using one finding, with increased sensitivity and negative predictive value. Combined > 50% decrease in diameter seen on B-mode ultrasound with PSV ratio ≥ twofold, relative to the proximal segment, showed the highest accuracy for diagno...

Long-Term Survival (27.7 Years) Following IV Antineoplaston Therapy (ANP) in a 36-Year-Old Female with a Progressive Diffuse Intrinsic Pontine Glioma (DIPG)

Stanislaw R Burzynski, MD, PhD, Tomasz Janicki, Gregory S Burzynski and Samuel Beenken

Article Type: Original Article | First Published: February 18, 2021

Long-term survival in Diffuse Intrinsic Pontine Glioma (DIPG) is very rare. The purpose of this report is to detail the early (1988) use of IV Antineoplaston therapy (ANP {A-10 + AS2-1}) and its efficacy in DIPG while presenting the 27.7-year survival of a 36-year-old patient treated with ANP for progressive DIPG. The patient presented in this manuscript was enrolled in BT-3, a Phase II protocol utilizing IV Antineoplastons A10 and AS2-1 (ANP). Tumor response was measured by bi-monthly MRIs of t...

X-Ray Film Reject Analysis in Radiology Departments of Port Sudan Hospitals

Fathi Awad, Fathalrahman Al Naem, Afrah Gemea, Nehad Wedaa, Zeinab Mohammed and Samah Tag Elser

Article Type: Original Paper | First Published: January 21, 2021

Patients normally go through repeated X-ray imaging procedures following the initial imaging exams are rejected because of poor image quality. Repeated images of radiological examinations increase the risk of radiation exposure of the patients, wastes medical resource, and reduce the quality of services of radiology department. Patients normally go through repeated X-ray imaging procedures following the initial imaging exams are rejected because of poor image quality. Repeated images of radiolog...
