Radiologic placement of subcutaneous infusion chest ports for long-term central venous access.
The technical success and complications associated with radiologic placement of subcutaneous implantable chest ports for long-term central venous access were evaluated. ⋯ With the benefit of both sonographic and fluoroscopic guidance, subcutaneous implantable chest ports can be inserted by radiologists with equal or lower complication rates than those reported in surgical series. Image-guided insertion of chest ports should replace rather than supplement unguided placement.

Comparative StudyComparison of HASTE and segmented-HASTE sequences with a T2-weighted fast spin-echo sequence in the screening evaluation of the brain.
The purpose of this study was to evaluate the neuroradiologic application of half-Fourier acquisition single-shot turbo spin-echo (HASTE) and segmented-HASTE (s-HASTE) sequences in comparison with a T2-weighted fast spin-echo sequence. ⋯ The HASTE and s-HASTE sequences afford substantial time reduction and also decrease motion artifacts and thus have potential advantages for neuroradiologic application, especially in uncooperative or unsedated children. The s-HASTE sequence may be preferable to the HASTE sequence because of fewer blurring artifacts and higher T2 contrast. However, small hyperintense and hypointense lesions may be overlooked when HASTE and s-HASTE sequences are used.
