Clinical Trial Controlled Clinical Trial
Adrenal gland hematomas in trauma patients.
To evaluate the frequency of detection of trauma-induced adrenal gland hematoma in current practice by using computed tomography (CT) and to correlate presence of adrenal hematoma with quantitative clinical indicators of injury severity. ⋯ Adrenal hematoma was detected in 51 (1.9%) of 2,692 trauma patients who underwent CT, or 0.8% of all patients (n = 6,808) entered in the trauma registry. Compared with the other trauma patients, the patients with adrenal hematomas had severe injuries associated with higher mortality.

Tagging with balanced steady-state free-precession (SSFP) magnetic resonance (MR) imaging by using a steady-state storage scheme for myocardial motion analysis was evaluated. Signal-to-noise ratio (SNR), blood-tissue contrast, and tag persistence in volunteers and phantoms showed improved performance of SSFP imaging with tagging compared with that of radiofrequency spoiled gradient-echo (SPGR) MR imaging with tagging. ⋯ Increased SNR and tag persistence can be achieved simultaneously with SSFP imaging compared with SPGR tagging methods. As a result, the proposed technique may be useful for analysis of diastolic ventricular function.

To assess clinical and surgical outcomes in patients with blunt abdominal trauma and negative screening ultrasonographic (US) scans. ⋯ The combination of negative US findings and negative clinical observation virtually excludes abdominal injury in patients who are admitted and observed for at least 12-24 hours.

To assess if T2-weighted magnetic resonance (MR) imaging provides added diagnostic value in combination with dynamic gadolinium-enhanced MR imaging in the detection and characterization of nodular lesions in cirrhotic liver. ⋯ T2-weighted MR imaging does not provide added diagnostic value in the detection and characterization of focal lesions in cirrhotic liver.
