Correlation between transient ischemic dilatation (TID) and coronary artery disease in Saudi male patients.

Objective: A high transient ischemic dilatation ratio (TID) for the left ventricle (LV) from a gated myocardial perfusion imaging (G-MPI) study is widely believed to be associated with significant coronary artery disease (CAD). We have investigated the relationship between TID and CAD for our male Saudi Arabian patient population.

Methods: In this retrospective study, all male Saudi Arabian patients who underwent a two-day G-MPI study using Tc99m MIBI during the year 2011 having a TID ⩾ 1.

A comparison of myocardial perfusion gated SPECT studies obtained at rest and after stress.

Objective: To perform a comparison between post-stress and rest gated single-photon emission computer tomography (SPECT) myocardial perfusion imaging (MPI) studies to assess post-stress stunning and the variables underlying this phenomenon.

Subjects And Methods: This was a prospective study of 318 consecutive adult patients undergoing stress and rest gated SPECT using a 2-day (99m)Tc-tetrofosmin protocol. Bruce protocol treadmill stress (n = 93) or i.

Sternal uptake on bone scintigraphy: age-related variants.

Background: When reporting bone scans, it is important to distinguish between normal variants and skeletal pathology involving the sternum. There are only limited reports dealing with age-related normal variants of the sternum on bone scintigraphy.

Methods: We have studied the age-related variants of sternal uptake on bone scintigraphy.
