摘要:

ABSTRACTAbdominal ultrasonograms were performed on 81 unselected patients with newly‐diagnosed nasopharyngeal carcinoma without clinical evidence of distant metastases. Two patients had ultrasongraphic features suspicious of, but not diagnostic of, hepatic metastases. One of these two patients developed hepatic metastases six months after the examination while the other was free of metastases at follow‐up 33 months afterwards. Of the 79 patients without evidence of metastases on ultrasonogram, two developed hepatic metastases after 22 and 32 months. Based on these results, we do not recommend abdominal ultrasonography as a routine staging investigation for nasopharyngeal carcin

摘要:

ABSTRACTUltrasound guided fine needle biopsies were performed in 69 patients with space occupying lesions in the liver. Fifty five of these patients had material obtained for both cytology and histology with a 22 gauge modified Menghini needle, while the other 14 were biopsied with a conventional Chiba needle. Results of cytology, histology of Menghini cores, and histology of cell blocks, were reviewed and correlated with the final diagnoses obtained by clinical review and follow‐up. Cytology detected 95% of malignant cases, and Menghini core histology detected 89%. A number of factors should determine the choice of fine needle biopsy for cytology or histology or bot

摘要:

ABSTRACTWe performed percutaneous ultrasound guided renal biopsy on 27 patients ages 16 to 76 years. A 14 gauge cutting needle was used. Twenty‐six patients had medical renal disease; one patient had a renal mass.Patients were followed by sonograms performed immediately post procedure as well the following day. Serum hemoglobin was obtained prior to the procedure as well as one day post biopsy.Complications included five small hematomas and one transient mild hydronephrosis secondary to blood clots. The hematomas were all first noted on the scan one day post biopsy.We conclude that ultrasound guided percutaneous renal biopsy is a safe procedure which is easily performed by the radiologis

摘要:

ABSTRACTDuplex Doppler ultrasound (DDU) is a non‐invasive and potentially accurate modality for assessing carotid bifurcation disease. It is however technically difficult and an appreciable learning curve has been identified. To assess the accuracy of DDU upon introduction into a radiology department with experienced sonographers and radiologists we reviewed the first twenty‐five (25) cases in patients, having both DDU and carotid angiography. Sensitivity of 95% and specificity of 81% were obtained for differentiating greater or less than 50% internal carotid artery diameter stenosis, and in detection of 80% or greater stenosis sensitivity and specificity were 83% and 100% respectively.We conclude that DDU is accurate when introduced into a department already competent in ultrasonography, with results being achieved similar to those reported from more experienced centres. Our results also support the appropriateness of the applied criteria for grading of carotid steno

摘要:

ABSTRACTThe features of hepatic congestion on computed tomography, ultrasound and nuclear medicine sulphurcolloid scans have been reviewed. Hepatic congestion may not be appreciated clinically, especially in the elderly, but the features described should be sufficiently characteristic to establish the diagnosis. The CT appearance may be confused with neoplastic infiltration, so that recognition of the condition may avoid further unnecessary investigations.

摘要:

SUMMARYInjury to the carotid or vertebral artery is an important clinical entity that requires angiography for definitive diagnosis and evaluation. The common carotid artery may be injured by penetrating trauma while the internal carotid artery is usually damaged by either trivial or blunt trauma.With trivial trauma extracranial internal carotid artery dissection should be considered if there is unilateral headache, Honer's syndrome or delayed transient ischaemic attack, and intracranial dissection if a profound neurological defect occurs immediately following trauma. Injury to the internal carotid artery following blunt trauma includes dissection of the extracranial internal carotid artery, carotid‐cavernous fistula and pseudoaneurysm formation. These should be considered in a patient with delayed neurological deficit, mandibular or skull fracture, a constellation of orbital signs or diffuse subarachnoid haemorrhage, respectively.Vertebral artery injury is less frequent. Dissection typically follows abrupt cervical rotation and occurs at C1‐2, whereas penetrating trauma may involve either the proximal or distal vertebral artery and occlusion, arteriovenous fistula or pseudoaneurysm may be found.Endovascular techniques may be used in either the carotid or vertebral artery to close fistulae or occlude an extensively damaged ves

摘要:

ABSTRACTCollapse of the left lower lobe is sometimes accompanied by linear atelectasis in the lingula. The lingular atelectasis may be more readily apparent than conventional signs of left lower collapse. The mechanism of this association as first described by Nordenström is discussed and its value as a diagnostic sign emphasised

摘要:

ABSTRACTIn July 1982 the Gastrointestinal Section of The Clinical Oncological Society of Australia began a multicentre randomized trial to assess the value of post‐operative pelvic radiotherapy in the local control of stage B and C carcinoma of the rectum. Patients who had undergone a potentially curative resection were randomized either to no further treatment (NO RT) or to pelvic radiotherapy (RT), 45 Gy in 25 fractions (plus a perineal boost of 5 Gy in 2 fractions after abdomino‐perineal resection).The trial was prematurely terminated in December 1985 owing to slow accrual after 70 patients had been randomized: 36 patients to RT and 34 patients to NO RT. Two patients in each group were found to be ineligible after randomization and, for a variety of reasons, thirteen patients who were randomized to RT did not receive that treatment. The incidences of post‐operative complications were comparable in both groups, indicating that radiotherapy produced no additional problems. Radiotherapy‐related morbidity comprised mainly diarrhoea (grade 1 = 2/21; grade 2 = 5/21; grade 3 = 0/21; grade 4 = 1/21). There were no deaths due to radiotherapy and only one patient, with grade 4 diarrhoea, failed to complete the prescribed course of radiotherapy. After an average follow‐up period of 52 months there were 15 local recurrences, 8 in the RT group and 7 in the NO RT group, giving an actuarial 2 year local recurrence rate of 16%. There was no difference in the time to local recurrence, either by randomization group (p=0.50) or by actual treatment received (p=0.91). Distant metastases occurred in 25 patients, 12 in the RT group and 13 in the NO RT group. Thirty one patients have died, 26 from cancer, 3 from intercurrent illness without evidence of cancer and two from surgical complications. There was no difference in survival time between the randomized groups: 16 deaths in the RT group and 15 deaths in the NO RT group (p=0.46). The only important factor predictive of local recurrence was age 65 years and over
