MRI evaluation of inflammatory activity in Crohn's disease.

Objective: We wanted to assess the capability of MRI to quantitatively evaluate the therapeutic response to Crohn's disease (CD) relapse.

Subjects And Methods: Twenty patients with histologically proven CD were prospectively evaluated with MRI and ileocolonoscopy over a 2-year period. The MRI protocol included axial and coronal T2-weighted and contrast-enhanced T1-weighted sequences.

New black blood pulse sequence for studies of the heart.

The black blood concept is based on the signal void principle of the sequences in Spin Echo, SE or FSE, which are very useful for studying the mediastinum and heart. In this setting, new sequences are continuously introduced to eliminate the artifacts caused by breathing and heart movements. One such sequence is the Double-IR preparation Black Blood FSE.

[Acute pancreatitis and acquired immunodeficiency syndrome].

Viral acute pancreatitis in Human Immunodeficiency Virus (HIV) infected patients has been occasionally described. We studied nine patients with HIV antibodies and acute pancreatitis attributed to Cytomegalovirus and/or Cryptosporidium infection. In four patients the clinical picture was consistent with acute pancreatitis while in five clinical manifestations were unspecific, and diagnosis was based on ultrasonography and/or computed tomography findings.
