Metal Artifact Reduction in Virtual Monoenergetic Spectral Dual-Energy CT of Patients With Metallic Orthopedic Implants in the Distal Radius.

Objective: The purpose of this study was to evaluate the image quality of virtual monoenergetic images obtained from dual-layer-detector spectral CT of patients with metallic orthopedic implants of the distal radius.

Materials And Methods: A retrospective analysis was performed between April 2016 and January 2017. Forty-three consecutively registered patients (33 women, 10 men; mean age, 50.

MRI of Cuboid Pulley Lesion.

Objective: The aim of this study was to describe cuboid pulley lesions and associated abnormalities on the basis of clinical findings and the results of MRI examinations of the ankle.

Materials And Methods: A retrospective search was performed to identify patients who had a cuboid pulley lesion during a 10-year period. A cuboid pulley lesion was defined as bone marrow edema in the lateroplantar ridge of the cuboid that was shown to be wrapped by the peroneus longus tendon on MRI of the ankle.

Ultrasound assessment of degrees of extrathyroidal extension in papillary thyroid microcarcinoma.

Objective: This study aimed to assess the diagnostic accuracy of ultrasound (US)-based T staging of papillary thyroid microcarcinoma (PTMC).

Methods: From January to June 2013, a total of 185 patients underwent preoperative thyroid US for the treatment of thyroid malignancy. A single radiologist immediately determined sonographic T staging for PTMC during real-time US examination.
