[Three-dimensional Visualization during CT Examination in Coxa Vara of Adolescents.]
Abstract:
The authors demonstrate two patients with adolescent epiphyseolysis of the head of the femur which is visualized by means of special software of so-called three-dimensional reconstruction of CT pictures. The preoperative visualization made it possible in the first case to define more accurately the surgical scheme of Southwick's two-plane osteotomy of the femur, in the second case the indication for Dunn's subcapital osteotomy of the neck of the femur. The subsequent postoperative visualization gives a spatial idea of the results of the two types of operations. In the discussion the authors deal with the range of indications for the use of the above software. Key words: computer tomography, three-dimensional visualization, coxa vara adolescentium, Southwicks and Dunn's osteotomy.

Imaging Studies III: Computed Tomography
Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
