Randomized Controlled Trial
Sonography of intrathyroid parathyroid adenomas: are there distinctive features that allow for preoperative identification?
The purpose of our study was to determine if intra-thyroid parathyroid adenomas can be accurately identified by applying proposed criteria to preoperative ultrasound examinations in patients with primary hyperparathyroidism. ⋯ Application of specific ultrasound criteria facilitates pre-operative diagnosis of intra-thyroid parathyroid adenomas and facilitates surgical planning. This large series confirms previous, largely anecdotal reports of ultrasound's utility in detecting intra-thyroid parathyroid adenomas.

The purpose of our study was to demonstrate that ultrasonography may allow a precise assessment of the course and relationships of the spinal accessory nerve (SAN). ⋯ The SAN can be clearly depicted by means of ultrasonography. Knowledge of the nerve's precise location, which may evidence individual variations, may have useful clinical applications.

To evaluate the economic impact of integrating coronary CT angiography (cCTA) or whole chest "triple-rule-out" CTA (TRO-CTA) in the work-up of patients with acute chest pain. ⋯ Integrating cCTA or TRO-CTA in a SOC algorithm can safely reduce the number of hospitalized patients and reduce total health care costs.

Comparative Study
Imaging differentiation of pathologic fractures caused by primary and secondary bone tumors.
To describe pre-treatment imaging features of pathologic fractures caused by primary bone tumors (PBTs) and metastatic bone tumors (MBTs) and determine if radiographic or cross-sectional features can differentiate the underlying pathologies associated with the fractures. ⋯ Pathologic fractures caused by PBT and MBT may be differentiated by a few specific radiographic and CT imaging features, though MRI was poor for characterization of the underlying lesion. Such knowledge may assist radiologists in raising the possibility of a PBT as the cause of a pathologic fracture.
