Immediate complications and pain relief associated with 296 fluoroscopically guided thoracic foraminal nerve blocks.
The goal of this work is to review the thoracic foraminal nerve blocks and foraminal epidurals performed at a single institution to determine the incidence and types of immediate complications and pain relief associated with thoracic foraminal nerve blocks. ⋯ Fluoroscopically guided thoracic foraminal nerve blocks are safe procedures and provide immediate partial or complete pain relief in a high percentage of patients.

Appropriateness of CT of the chest, abdomen, and pelvis in motorized blunt force trauma patients without signs of significant injury.
The purpose of this article is to determine the frequency of clinically significant injuries detected on CT of the chest, abdomen, and pelvis in adult patients involved in motorized blunt force trauma with normal clinical examinations. ⋯ The clinical yield of performing CT of the chest, abdomen, and pelvis in motorized blunt trauma patients with normal clinical examinations in our study was minimal.

Catheter-induced aortic dissection after invasive coronary angiography: evaluation with MDCT.
The purpose of this study was to describe the MDCT findings of retrograde aortic extension of catheter-induced coronary artery dissection and the use of MDCT in follow-up of this complication. ⋯ Coronary artery dissection with aortic extension can be a fatal although infrequent complication. The coronary artery entry point is usually stented in the catheterization laboratory. Thereafter, CT is the imaging modality of choice for immediate confirmation of the presence of residual iatrogenic aortic dissection and evaluation of its extent and later noninvasive follow-up.

The purpose of this article is to evaluate the use of the periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER) technique for artifact reduction and overall image quality improvement for intermediate-weighted and T2-weighted MRI of the shoulder. ⋯ The PROPELLER technique for MRI of the shoulder reduces the number of sequences with diagnostic impairment as a result of motion artifacts and increases image quality compared with standard TSE sequences. PROPELLER sequences increase the acquisition time.

Utility of ultrasound and MRI in prenatal diagnosis of placenta accreta: a pilot study.
The purpose of this study was to evaluate transabdominal pelvic ultrasound and MRI for the prenatal diagnosis of placenta accreta. ⋯ The accuracy of MRI may improve if volumes of low-signal-intensity bands are calculated, MRI is performed before 30 weeks' gestation, and risk factors for placental insufficiency are recognized.
