The ANTARES collaboration is building a deep sea neutrino telescope in the Mediterranean Sea. This detector will cover a sensitive area of typically 0:1 km 2 and will be equipped with about 1000 optical modules. Each of these optical modules consists of a large area photomultiplier and its associated electronics housed in a pressure resistant glass sphere.… (More)
Solitary eosinophilic granulomas of bone are benign and tend to heal spontaneously over a period of months to years. Radiotherapy and curettage have certain risks, which may be excessive considering the benign nature of the lesion. The authors injected methylprednisolone directly into 9 pathologically proved solitary eosinophilic granulomas of bone and… (More)
Percutaneous fine needle aspiration biopsy of 18 patients with pancreatic masses, and 19 with other intra-abdominal tumors, showed it to be a safe, accurate procedure. A diagnostic biopsy yield was obtained in over 85% of the cases without clinical complications. Indications for fine needle biopsy are: (a) to avoid surgery by obtaining a histologic… (More)
Ten patients with small intestinal excavating metastatic lesions are described. Cavitation of a mass is a generally unrecognized appearance of metastatic disease to the small intestine and should be considered in the differential diagnosis of small bowel excavation.
Six patients with primary ulcerative carcinoma of the esophagus are described. The radiologic appearance is analogous to the Carman-Kirklin complex seen with gastric malignancies. The clinical course of this uncommon type of esophageal carcinoma is the same as the more common constricting and polypoid varieties.
Ultrasound and computed tomography (CT) guided percutaneous needle biopsy of soft tissue lesions was performed in 39 patients. A correct diagnosis was obtained in 35 of 42 biopsies, with an overall accuracy rate of 83%. No false-positive diagnoses were obtained, and no complications related to the procedure were encountered. The value of this technique in… (More)
The response to intraarterial cis-diamminedichloroplatinum II (CDP) chemotherapy was evaluated by computed tomography (CT) in 33 patients with pathologically proved osteosarcoma of the long or flat bones. Twenty-one of the 33 patients had a CT scan before chemotherapy was started. In the other 12 patients, a CT scan was obtained after at least two courses… (More)
CT scans demonstrated a localized collection of gas adjacent to a normal sacroiliac joint in 5 patients. In each case the lesion was sharply demarcated by a thin sclerotic rim. A benign bone cyst was confirmed histologically in 2 cases. The radiologist should be aware of this appearance so as to avoid invasive procedures based on a misdiagnosis of infection… (More)
