Cardiac involvement in Mulibrey nanism: characterization with magnetic resonance imaging.

Mulibrey nanism (MUL) is an autosomal recessive disorder that is enriched in the Finnish population. Variable degrees of pericardial and myocardial involvement can lead to heart failure and premature death. The purpose of this study was using magnetic resonance imaging (MRI) to assess structural and functional abnormalities of the MUL cardiopathy in all four cardiac chambers as well as in the pericardium.

Evaluation of methods for MR imaging of human right ventricular heart volumes and mass.

Purpose: To assess the utility of two different imaging directions in the evaluation of human right ventricular (RV) heart volumes and mass with MR imaging; to compare breath-hold vs. non-breath-hold imaging in volume analysis; and to compare turbo inversion recovery imaging (TIR) with gradient echo imaging in RV mass measurement.

Material And Methods: We examined 12 healthy volunteers (age 27-59 years).

Carotid and femoral artery stiffness in Takayasu's arteritis. An ultrasound study.

Purpose: To determine the stiffness of large arteries in patients with Takayasu's arteritis (TA).

Materials And Methods: A noninvasive ultrasonic method was used to measure Peterson's elastic modulus (Ep), Young's elastic modulus (YM). and the stiffness constant beta of the common carotid arteries in 13 and of the common femoral arteries in 16 patients with TA and in healthy control subjects.

Magnetic resonance imaging angiography in patency evaluation of bronchial artery revascularization grafts.

In this report we present our experience of non-invasive magnetic resonance imaging (MR) angiography and selective catheter angiography in assessing the patency of bronchial artery revascularization grafts after an en bloc double-lung and heart-lung transplantation. We studied 8 patients who had undergone pulmonary transplantation with direct bronchial artery revascularization. Catheter angiography was performed 10 days to 63 months postoperatively.
