Sublingual nitroglycerin spray significantly dilates the coronary arteries and allows more septal branches to be visualized at coronary CT angiography without diminishing image quality or increasing the number of side effects.

Background: Multi-detector computed tomography angiography (MDCTA) has been increasingly used in the evaluation of the coronary arteries. The purpose of this study was to review the literature on the diagnostic performance of MDCTA in the acute setting, for the detection of non-ST-elevation myocardial infarction (NSTEMI) and unstable angina pectoris (UAP).

Background: Multi-detector computed tomography angiography (MDCTA)of the coronary arteries after stenting has been evaluated in multiple studies.

Sclerotic lesions of the jaw are uncommon but may be clinically relevant. In this pictorial review, the most common sclerotic lesions are discussed. Three categories of lesions are distinguished; odontogenic sclerotic lesions, non-odontogenic sclerotic lesions, and mixed lytic-sclerotic lesions. In each group, non-neoplastic conditions are discussed first, followed by benign and malignant neoplasms. For each disease a brief overview is given, including histological features, epidemiology, symptoms, typical location, imaging features, and treatment. This review emphasizes which basic observations are essential to the evaluation of sclerotic jaw lesions and what elements have to be taken into account to create a proper differential diagnosis.
