Comparative StudyFast breath-hold T2-weighted MRI of the kidney by means of half-Fourier single-shot turbo spin echo: comparison with high resolution turbo spin echo sequence.
The value of the fast half-Fourier single-shot turbo spin echo (HASTE) sequence in T2-weighted MRI of the kidney was evaluated as a substitute for the conventional turbo spin echo (TSE) sequence. ⋯ The HASTE sequence generates high contrast images and is free of motion and chemical shift artifacts, with much better time efficacy. The sequence provides comparable diagnostic information to TSE sequences.

Case ReportsIdentification of pulmonary vein stenosis after radiofrequency ablation for atrial fibrillation using MRI.
Pulmonary vein stenosis is one of the frequent complications after radiofrequency ablation for atrial fibrillation. MRI plays an important role in depicting the pathoanatomic structure of the pulmonary veins, and measuring the blood flow velocity in the pulmonary veins before and after therapy, and is superior to transesophageal echocardiography for this purpose.

Pictorial essay. Various locations of cystic and alveolar hydatid disease: CT appearances.
Hydatid disease (echinococcosis) is a parasitic infection caused by the larval stage of the tapeworm Echinococcus. In humans, the two main forms are cystic hydatid disease, caused by E. granulosus, and less frequently alveolar hydatid disease, caused by E. multilocularis. They can be found in various sites in the body. The purpose of this essay is to illustrate the CT appearances of cystic and alveolar hydatid disease in various locations.
