Introduction: Radiological assessment of neurovascular disease processes often requires multiple contrast-enhanced and non-contrast enhanced exams over a large FOV. We define a comprehensive neurovascular exam (CNVE) as the high resolution imaging of four major vessel groups: the aortic arch and great vessel origins, the carotid artery bifurcations and vertebral-basilar system, the intracranial...

This report presents different approaches to solving sparse linear systems—direct and iterative solvers—and compares a number of methods in each category. I also consider the two techniques of using solvers for linear systems: single method solver schemes and multi-method solver schemes. I also present some of the popular systems that use these techniques. This involves surveying the relevant l...

BACKGROUND & OBJECTIVES In recent decades, many studies have been carried out on the importance of Kolb experiential learning theory (ELT) in teaching-learning processes and its effect on learning outcomes. However, some experts have criticized the Kolb theory and argue that there are some ambiguities on the validity of the theory as an important predictor of achievement. This study has been ca...

In this paper, we are introducing a new method of granular exam-to-slot allocation based on the preprocessing of the basic student-exam information into a more abstract (granulated) entity of conflict chains. Since the conflict chains are designed to capture the mutual dependencies between exams, they enable us to reason about the exam-to-slot allocation for all exams in a chain rather than jus...

Many years ago, longer than I may care to admit, I had to take my Board Exam in Pulmonary Medicine. I decided to prepare for the exam by reading a reference textbook cover-to-cover. Because Dr Gerald Baum had been one of my favorite teachers while I was a medical student in Cleveland, I naturally felt inclined towards an earlier edition of Baum’s Textbook of Pulmonary Medicine. It was a most fo...

Pulmonary arterial hypertension (PAH) is characterized by elevated pulmonary artery (PA) pressure, which negatively affects the right ventricular (RV) function. This report shows a patient with severe PAH, on whom a comprehensive MRI exam was performed to evaluate both PA and RV. New imaging sequences were implemented for obtaining additional parameters about the patient's condition. The result...

BACKGROUND In Iran, admission to medical school is based solely on the results of the highly competitive, nationwide Konkoor examination. This paper examines the predictive validity of Konkoor scores, alone and in combination with high school grade point averages (hsGPAs), for the academic performance of public medical school students in Iran. METHODS This study followed the cohort of 2003 ma...
