In order to reveal abnormalities in the soft tissue of the anterior part of the knee, caused by protracted mechanical stress, we performed ultrasound studies of both knees of 95 male workers in the carpet-laying and parquet floor trade (group 1). Seventy-three painters (group 2) served as controls. In group 1, an anechoic fluid collection was detected in 10(More)
The results of 155 US-guided cutting needle biopsies, mainly of abdominal and transthoracic lesions, were reviewed to assess the diagnostic accuracy of the method. A fine needle biopsy (FNB) was additionally performed in 99 of the patients. Sufficient material for histologic and cytologic analysis was obtained in 88% (137/155) and 98% (97/99), and a correct(More)
Sixteen patients with biochemically proven primary hyperparathyroidism (PHPT) underwent ultrasonography (US), fine-needle aspiration (FNA) for cytologic sampling (n = 9), or intact parathormone assay (n = 3) before operation (n = 15) in order to determine the accuracy of the methods. Pre-operative US was found sensitive (100 per cent), but two thyroid(More)

The purpose of the work was to investigate: Whether osteoarthritis of the hip can be divided into radiologic classes by examining the tendency of osteoarthritis of the hips to increase the growth and calcific content of the bone on the one hand and the associated loss of calcium and cartilage and the deformation and destruction of bone on the other. The(More)
We reviewed the results of 187 consecutive ultrasound-guided fine-needle biopsies of the pancreas in 171 patients to assess the diagnostic accuracy of the method. The final diagnosis obtained at operation, autopsy or follow-up were: adenocarcinoma (n = 83), metastatic cancer (n = 11), cystadenocarcinoma (n = 2), lymphoma (n = 2), malignant gastrinoma (n =(More)
The imaging findings in 134 patients with primary liver malignancy were evaluated retrospectively to determine the sensitivity and appearances of the tumour by each method. One hundred and thirty-one patients were examined by ultrasound, 77 via computed tomography, 62 via arteriography, 30 were subjected to isotope examination, and fine-needle biopsies were(More)
