[Magnetic resonance (MR) imaging of the normal mediastinum].

Magnetic Resonance (MR) cross sectional images of the normal mediastinum are presented and discussed. In normal subjects most mediastinal structures visible on Computed Tomography (CT) are also visible using MR. The primary advantages of MR over CT in the evaluation of mediastinum are the greater soft tissues contrast resolution, the multiplanar (axial, coronal and sagittal) display of the mediastinal anatomy and its ability to distinguish vascular from nonvascular structures without injection of contrast media.

[Computerized tomography: analysis of the characteristics of various pieces of equipment].

Spatial resolution, statistical noise and patient dose are important parameters for the evaluation of the performances of CT-scanners. These parameters may be combined to develope some "synthetic indices", able to describe intrinsic properties of a CT-scanner (the maximum obtainable spatial resolution and dose efficiency). This type of analysis has been applied to the evaluation of four CT-scanners, three of 3rd and one of 4th generation.

[Dosimetry problems in irradiation of mediastinal tumours (author's transl)].

Various physical parameters are described for evaluation of the quality of the irradiation plane. Of these, the integral dose and the dose gradient index are regarded as particularly significant and their calculation is included in a computerised dosimetry programme. Examples are drawn from the comparison of various mediastinum irradiation techniques: 60Co, high energy X-rays, fast electrons.

Image quality and dose in computerized tomography: evaluation of four CT scanners.

Spatial resolution, statistical noise, and patient dose are important parameters for the evaluation of the performances of computerized tomography (CT) scanners. These parameters are combined to develop some "synthetic indices," and to be able to describe intrinsic properties of a CT scanner (the maximum obtainable spatial resolution and dose efficiency). This type of analysis has been applied to the evaluation of four CT scanners, three of third, and one of fourth generation.
