RESUMO
On T1 weighted pulsing sequences, the majority of soft tissue masses are of low signal intensity and show high intensity signals on T2 weighting. There however is a subset of soft tissue masses of varied histology that shows high signal intensity on T1 weighted pulsing sequences. These masses have either fat or blood in their substance. Lipomatous and hemangiomatous lesions that did not show high-signal intensity on T1 weighting were also encountered and are discussed. Present experience with MRI of soft tissue masses suggests that there is a limited spectrum of entities that produce high-signal intensity T1 weighted soft tissue masses.

The intra-aortic balloon pump has been proven to be an effective form of therapy in a variety of situations involving actual or potential ventricular power failure. An experience with 12 newly-designed percutaneous PERCOR-TM intra-aortic balloon pumps is discussed. Emphasis is made on the ease of insertion and removal, and on the fact that a trained surgical team in an operating room setting is not necessary. Effectiveness of the balloon in comparison to the traditional intra-aortic balloon pump is also discussed.
