摘要:

ABSTRACTRadiologists have all too often been vague about mammographic problems presenting on films. Their reports are often too equivocal. However, with a thorough mammographic evaluation, most lesions can be classified as benign, malignant or spurious. We have listed thirteen positions, apart from the routine craniocaudal and oblique views, that may help decide the malignant potential of a mammographic problem.

摘要:

ABSTRACTTwo hundred and three consecutive patients underwent mammography at both public and private facilities. Their patients were asked to complete a questionnaire which recorded their assessments of pain. There was a very low incidence of significant pain (4%). The rate was highest (10.9%) in those with pre‐existing breast pain. This compared with a rate of 1.4% in those without pre‐existing breast pain. A large number of premenopausal women suffered from breast pain (69%). Breast pain was particularly common in the week prior to onset of menstruation. Therefore, routine mammography should be scheduled in a pain‐free interval and, if possible, the week prior to onset of menstruation should be av

摘要:

ABSTRACTDuring a 12 month period of operation of a 0.3 Tesla MRI iron cored resistive scanner 74 cases of syr‐ingomyelia were diagnosed on clinical, radiological and/or surgical grounds. Without knowledge of any clinical or radiological data the syrinxes were classified into five groups — idiopathic, idiopathic associated with Chiari malformation, tumour associated, post‐traumatic and arachnoiditis associated — and the lesion characteristics within each group were compared.Although MRI was extremely sensitive in picking up even small syrinxes, there was considerable overlap of MRI characteristics across the sub‐groups, so that two post‐traumatic syrinxes had lesion characteristics identifiable with those of tumour syrinx and one in‐tramedullary tumour syrinx had the MRI characteristics of a benign, idiopathic syrinx. It is concluded that meticulous attention to technique, including axial as well as sagittal T1 weighted sequences, and the administration of intravenous paramagnetic contrast media are necessary for detection and accurate classificatio

摘要:

ABSTRACTA retrospective review of initial and subsequent CT scans of 179 children who has suffered severe head injury requiring admission to intensive care was performed. The aim was to define the CT appearance which was always associated with a poor outcome. The children whose brain showed poor definition of basal ganglia and grey‐white differentiation overall, together with sufficient swelling to obliterate the ambient cistern and third ventricle always died or remained in a vegetative state. Over half of these had reduced brain density, and several had small focal high densities consistent with contusions or petechial haemorrhages. A typical appearance showed homogeneous scans at the levels of the ambient cistern and thalami with no normal internal brain detail. Conversely obliteration of the ambient cistern associated with a large surface collection was compatible with complete recovery if grey‐white definition remained normal and treatment was pro

摘要:

SUMMARYThirteen cases of juvenile angiofibroma were treatea surgically with preoperative embolisation. One case occurred in a female. Embolisation significantly reduced blood loss and allowed complete surgical removal of the tumour in all cases. No significant complications occurred. Preoperative embolisation should be employed routinely in the surgical management of these patients.

摘要:

ABSTRACTThis study attempts to find out what is the appropriate dose of non‐ionic contrast media to provide an acceptable study at the lowest possible cost.139 adults with normal renal function were studied. Four different dose regimes were employed and a standardised set of I.V.U. films were obtained. These were reviewed by two independent assessors who were unaware of the dose regime used. Each I.V.U. was scored on a modified Fry regime.This survey showed a clear relationship between quality and dosag

摘要:

SUMMARY30 children with Ewing's sarcoma, the most common malignant pelvic tumour in childhood, were analysed. The diagnosis of Ewing's sarcoma is relatively easy and can be established in most of the cases on plain radiography. The diagnostic radiographic features of the tumour are discussed. The two most important conditions in differential diagnosis are eosinophilic granuloma and the rare primary bone lymphoma. Osteomyelitis should rarely cause confusion unless the clinico‐radiographic findings are not properly evaluate
