Die kernspinresonanztomographische Darstellung des Korpuskarzinomes ohne und mit Applikation des paramagnetischen Kontrastmittels Gd-DTPA

Abstract

Patients with a corpus carcinoma were examined by magnetic resonance imaging before and after application of the paramagnetic contrast agent Gd-DTPA. The images were obtained by spin echo technique with the repetition times 0.5 s or 1.8 s and the echo times 35/70 ms. The dosis of the contrast agent was 0.1 mmol per kg body weight. The contrast between myometrium and tumour increased after injection of the contrast agent and structures within the tumour can be better differentiated. The pelvic organs (bowel and urinary bladder) can be seen in greater detail. Images taken with short repetition times after application of Gd-DTPA show greater contrast than pictures picked up with the same imaging parameters without contrast agent. Furthermore, there is an improvement compared with images taken with long repetition times.
