Spinal tuberculosis presenting with hip abscesses: a diagnostic challenge.

Spinal tuberculosis is the most common manifestation of extra-pulmonary tuberculosis. It is difficult to diagnose the disease due to its insidious onset and non-specific clinical presentation. A high degree of suspicion and appropriate imaging studies are necessary for its early diagnosis and treatment.

Correlation between myocardial scintigraphy and CT angiography in the evaluation of coronary disease.

Background: Coronary multidetector CT angiography (CTA) has shown good accuracy for detection of coronary stenosis. Although this is a promising technique for the evaluation of CAD, its correlation with the functional expression of the disease is not yet well established.

Objective: To evaluate whether the presence of CAD and the degree of coronary stenosis assessed by CT angiography are associated with changes in the Myocardial Perfusion Scintigraphy (MPS).
