A total of 267 patients referred for ultrasound examination because of clinical suspicion of ectopic pregnancy were studied prospectively. The outcome was correlated with the ultrasound findings and human chorionic gonadotrophin levels using a quantitative serum assay. The value of the following in the diagnosis of ectopic pregnancy are assessed: ultrasound criteria for early diagnosis of intrauterine pregnancy before visualization of a viable fetus, the discriminatory zone of hCG and extrauterine abnormalities.

Twenty-one patients with established cystic fibrosis were examined using high-resolution, narrow-section computed tomography. The bronchiectasis of cystic fibrosis is described and is shown to be characteristic in many respects. Computed tomography was found to be more accurate than standard radiography in locating the disease process and demonstrated pleural involvement which was not apparent on chest radiographs.

The indication for and results of radiological examination of the pharynx in 195 young adults (83 men, 112 women; age 13-40 years) were analysed retrospectively. A total of 99 patients were examined because of a suspected foreign body. In only seven was a foreign body revealed; two patients had mucosal tears. ⋯ Our results show that a careful radiological examination of the pharyngeal function is of value in young adults with swallowing complaints. Even in acute dysphagia a foreign body is seldom revealed. In patients who had undergone cineradiography, 21 of 90 (23%) had some form of pharyngeal dysfunction which could account for the patients' symptoms.
