Learning curve of speech recognition.

Speech recognition (SR) speeds patient care processes by reducing report turnaround times. However, concerns have emerged about prolonged training and an added secretarial burden for radiologists. We assessed how much proofing radiologists who have years of experience with SR and radiologists new to SR must perform, and estimated how quickly the new users become as skilled as the experienced users.

Mesh-based method for measuring intracranial volume in patients with craniosynostosis.

Purpose: Craniosynostosis may lead to reduced intracranial volume (ICV) and disturb normal brain growth and development. Thus, ICV is an important parameter with respect to the surgical outcome. Current methods for ICV determination from computed tomography (CT) images have drawbacks.

Background: Management of severe liver injuries has evolved to include the options for nonoperative management and damage control surgery. The present study analyzes the criteria for choosing between nonoperative management and early surgery, and definitive repair versus damage control strategy during early surgery.

Methods: In a retrospective analysis of 144 patients with severe (AAST grade III-V) liver injuries (94% blunt trauma), early laparotomy was performed in 50 patients.

Postoperative MDCT of tibial plateau fractures.

Objective: The purposes of this retrospective study were to elaborate our experience in postoperative MDCT of tibial plateau fractures, to establish the frequency of these fractures and the indications for MDCT, and to assess the common findings and their clinical importance.

Measurement of spinal canal narrowing, interpedicular widening, and vertebral compression in spinal burst fractures: plain radiographs versus multidetector computed tomography.

Objective: To assess the reliability of measurements of spinal canal narrowing, vertebral body compression, and interpedicular widening in burst fractures in radiography compared with multidetector computed tomography (MDCT).

Materials And Methods: Patients who had confirmed acute vertebral burst fractures over an interval of 34 months underwent both MDCT and radiography. Measurements of spinal canal narrowing, vertebral body compression, and interpedicular widening from MDCT and radiography were compared.

MRI of acute meniscal injury associated with tibial plateau fractures: prevalence, type, and location.
