Comparative StudyComparison of 3-T MRI and arthroscopy of intrinsic wrist ligament and TFCC tears.
This study assesses the sensitivity and specificity of MRI at 3 T compared with arthroscopy for detection of intrinsic wrist ligament and triangular fibrocartilage complex (TFCC) tears. ⋯ MRI at 3 T is sensitive and specific for detection of wrist ligament tears. MR arthrography is more sensitive for ligament evaluation but can result in false-positive findings because of microperforations.

Cardiac MRI and pulmonary MR angiography of sinus venosus defect and partial anomalous pulmonary venous connection in cause of right undiagnosed ventricular enlargement.
Patients may be referred for cardiology assessment because of an enlarged right ventricle (RV) with no cause apparent on echocardiography. Cardiac MRI can contribute to the management of these patients by detecting sinus venosus defect or partial anomalous pulmonary venous connection (PAPVC). We sought to show how often sinus venosus defect or PAPVC was detected on MRI in patients with an enlarged RV without a previously established definite diagnosis. ⋯ This article about cardiac MRI in adults with sinus venosus defect and PAPVC shows that cardiac MRI can reliably detect and quantify these lesions when other methods have not provided a complete diagnosis for the cause of right heart enlargement.

Alphabetic bias in the selection of reviewers for the American Journal of Roentgenology.
This study was performed to determine whether the number of invitations extended to American Journal of Roentgenology (AJR) reviewers is biased toward reviewers with last names that start with early letters of the alphabet. ⋯ During the study period, there is clear evidence of bias toward reviewers whose last names begin with a letter at the beginning of the alphabet. This bias is both statistically and clinically significant, with reviewers with names starting with letters at the beginning of the alphabet invited to review almost twice as often as those with names starting with letters toward the end of the alphabet. This bias is most likely due to "satisfaction of search" by the assigning editors who tend to invite the first panel of reviewers who meet their criteria on a list of names presented to them in alphabetic order. Reviewers' good will can be enhanced if particular alphabetic groups are not overloaded with reviews. Journal editors can help to avoid this bias by consciously spreading review invitations evenly throughout the whole alphabet. Redesign of editorial workflow software could help to avoid this alphabetic bias.

Clinical TrialDiagnostic and interventional MRI of the sacroiliac joints using a 1.5-T open-bore magnet: a one-stop-shopping approach.
The objective of our study was to prospectively test the hypothesis that combined diagnostic and interventional MRI of the sacroiliac joints can be performed efficiently and effectively. ⋯ We accept the hypothesis that combined diagnostic and interventional MRI of the sacroiliac joints can be performed efficiently and effectively for comprehensive diagnosis and therapy of lower back pain originating from the sacroiliac joints.

MDCT evaluation of blunt abdominal trauma: clinical significance of free intraperitoneal fluid in males with absence of identifiable injury.
The purpose of our study was to determine the clinical significance of the isolated finding of free intraperitoneal fluid on 64-MDCT in male patients who have undergone blunt trauma. ⋯ With 64 MDCT, the isolated finding of free intraperitoneal fluid in male patients who have undergone blunt trauma is seen in approximately 3% of patients. The size and mean attenuation coefficient measurements may add useful information regarding the clinical management of these patients, suggesting that small amounts of low-attenuation free fluid, in the absence of identifiable injury, may have no significant clinical implications.
