Routine chest and abdominal high-pitch CT: an alternative low dose protocol with preserved image quality.

Objective: To investigate the radiation dose and image quality of the high-pitch dual source computer tomography (DSCT) for routine chest and abdominal scans.

Methods: 130 consecutive patients (62 female, 68 male, median age 55 years) were included. All patients underwent 128-slice high-pitch DSCT (chest n=99; abdomen n=84) at a pitch of 3.

Quantitative analysis of muscle and tendon retraction in chronic rotator cuff tears.

Background: Musculotendinous retraction is a limiting factor for repair of long-standing rotator cuff tears. However, it is currently unknown to what extent the muscle and tendon contribute to the degree of total retraction. Further understanding of this may possibly influence the strategy of musculotendinous reconstruction.
