    Notizen: Summary. We assessed the ability of magnetic resonance, a recently introduced imaging technique, to demonstrate the maternal anatomy in obstetrics. The signal intensity of different maternal tissues using T1 and T2 weighted sequences was examined. The bony pelvis is depicted with sufficient clarity to provide an alternative to conventional X-ray pelvimetry. The placenta and cervix have a distinctive appearance facilitating the diagnosis of placenta praevia. The unique demonstration of cervical morphology will offer the potential for investigation into the illunderstood conditions of cervical dystocia and cervical incompetence.

    Notizen: Summary. Twenty-five women with primary carcinoma of the cervix were examined with magnetic resonance imaging (MRI). A number of different pulse sequences with T1 and T2 weighting were employed to determine optimum tissue contrast, and the potential for staging cervical cancer was assessed and compared with the clinical findings. MRI is seen to give a unique view of cervical cancer in particular in stage I and II disease where other imaging techniques have known limitations. In addition, stages III and IV were well seen with demonstration of tumour comparable with that of computerized axial tomography (CT).

    Notizen: Summary. Magnetic resonance imaging (MRI) was performed in 36 patients at between 10 and 38 weeks gestation to determine the fetal anatomy that could be identified at different gestations. Fetal motion significantly degraded the image quality in the first and second trimesters, but in the final trimester fetal anatomy was clearly demonstrated. T2 weighted sequences showed the fetal brain and lungs to have a high signal intensity. Shorter TR leading to a T1 weighting gave better resolution of the overall anatomy. MRI has revealed the potential for assessment of lung maturity and the growth-retarded fetus.

    Notizen: Abstract Eighteen patients with suspected primary or recurrent ovarian carcinoma have been investigated in each case by the assay of serum levels of the antigen CA125, immunoscintigraphy using131I-OC125 antibody and magnetic resonance imaging using a 0.15 Tesla-system. The final diagnosis was confirmed by laparotomy or laparoscopy. Serum levels of CA125 ranged between 5 and 780 units/ml (normal range 〈 35). Antibody images and MRI were truly positive in 11 patients, 2 of whom were subsequently found to have bowel tumours. MRI showed greater detail of smaller lesions whilst immunoscintigraphy was more suited to the detection of distant metastases. In 7 patients the antibody images were positive whilst the serum marker levels were normal. This pilot study provides a preliminary comparison of the more recent techniques currently being evaluated for the detection of ovarian carcinoma.
