Comparative Study
[CT-based software-supported prediction of the postoperative lung function after partial resection of the lung].
The predicted postoperative forced exspiratory volume in one second (FEV (1)) is an important functional factor for predicting the operability of patients with bronchial carcinoma. A software tool that uses a preoperative chest MSCT and pulmonary function test (PFT) for largely automated prediction of the FEV (1) was evaluated. ⋯ In the present pilot study the software-assisted prediction of the postoperative FEV (1) using a preoperative MSCT and pulmonary function test corresponded satisfactorily with the observed postoperative values. The introduced approach may make it possible to obtain additional information for the prediction of functional operability prior to performing lung cancer surgery.

The term whole-body magnetic resonance imaging (MRI) covers a whole series of different MRI techniques that can be used for detecting various diseases. Whole-body magnetic resonance angiography facilitates the visualization of the entire arterial system from head to toe with the exception of the coronary arteries. Whole-body MRA is clinically used for therapy planning in patients with multiple stenoses and may be able to be used in the future as a screening method for high risk populations, for example in patients with coronary heart disease. ⋯ Fast contrast-enhanced sequences can be used as an alternative approach in the search for tumors. Whole-body MRI can even be superior to a combination of positron-emission tomography and computed tomography in the detection of distant metastases. This article presents the recent developments in whole-body MRI and its established indications, which in the future might lead to a change in the paradigm for the diagnostic work-up of many diseases.

Development of a feasible and reliable method for determining abdominal fat using breath-hold T1-weighted magnetic resonance imaging. ⋯ The described method facilitates reliable determination of abdominal fat within a reasonable period of time. Using breath-hold MR sequences, the time of examination is less than 5 minutes per patient.
