Randomized Controlled Trial Multicenter Study Comparative Study
[Diagnostic value of whole-body MRI and bone scintigraphy in the detection of osseous metastases in patients with breast cancer--A Prospective Double-Blinded Study at two Hospital Centers].
The purpose of this study was to compare the diagnostic accuracy of whole-body MRI (WB-MRI) and bone scintigraphy (BS) for the screening of bone metastases for the first time in a large and homogeneous patient collective with breast cancer in a systematic and controlled study. ⋯ It could be demonstrated that WB-MRI is superior to BS for detecting bone metastases in breast cancer patients. These results should be considered for the next version of the S 3 guideline "Diagnosis, Therapy and Follow-Up of Breast Cancer".

A computer program was created to train technologists to perform chest X-rays in crying infants at maximum inspiration. ⋯ The ability of a technologist to take a chest X-ray at optimal inspiration in a crying child is improved by the tested computer program.

To evaluate a 3D model of the left ventricle (LV) which allows calculation of LV function parameters on the basis of both short axis (SA) and long axis (LA) cine acquisitions. Comparison with the conventional Simpson's rule method in a volunteer and patient collective. ⋯ The proposed 3D shape model allows merging of information acquired in different orientations and thus the combination of SA and LA contours with better coverage of the left ventricle. It provides a suitable fit with a reduced number of segmented contours.

The purpose of this study was to compare the depiction of intracranial aneurysms by 3D time-of-flight (TOF) magnetic resonance angiography (MRA) at 7 Tesla (T) with the clinical standard TOF MRA at 1.5 T and with digital subtraction angiography (DSA). ⋯ Our initial results indicate that image quality of intracranial aneurysms may benefit from the increased spatial resolution of 7 T TOF MRA compared with 1.5 T TOF MRA. Tailored scan protocols and optimized radiofrequency head coils are needed to further improve the image quality of 7 T TOF MRA.

To determine the added diagnostic benefit of using MS-CT in multiple trauma patients differentiated by severity of injury and affected body region. ⋯ Compared with conventional radiography and ultrasound in the emergency room, 16-row whole-body spiral CT yields numerous additional and new findings in different body regions in patients with multiple traumas. New findings primarily involved the head, and the additional findings involved the chest, pelvis, and spine. Most findings obtained with CT were potentially life threatening (ATLS class 2).
