C-scan ultrasonography in orbital diagnosis.
A C-scan imaging facility has recently been added to the ultrasonic system in use at Moorfields Eye Hospital, London. The technique is explained and typical C-scans are presented to demonstrate the normal orbital fat and optic nerve, together with selected pathological conditions in the orbit. The C-scan facility permits imaging of the orbital contents in the coronal plane. This coronal plane i...
متن کاملB-scan ultrasonography of orbital lymphangiomas.
Unilateral exophthalmos is an important clinical ophthalmic problem. A clinical diagnosis of the cause of the exophthalmos is often very difficult. B-scan ultrasonography is an important new diagnostic modality with great potential in determination of the nature of orbital pathology. The earliest ophthalmic applications of ultrasound were reported by Mundt and Hughes (I956). A-scan ultrasound, ...
متن کاملOrbital ultrasonography for diagnosis and evaluation of retrobulbar vascular disorders
Diagnostic and differential diagnostic of orbital diseases are considered to be one of the most difficult problems in ophthalmology because most orbital pathologies display the same signs and symptoms. Condition of orbital tissues can be evaluated using three different radiology imaging techniques: A/B-scan ultrasonography, computed tomography, and magnetic resonance imaging. A/B-scan ultrasono...
متن کاملDiagnosis of thromboembolic disease: Combined ventilation perfusion lung scan and compression ultrasonography
The clinical management of pulmonary embolism and deep venous thrombosis of the legs are similar and requires prolonged anticoagulation therapy. The standard diagnostic approach in patients suspected of pulmonary embolism is ventilation-perfusion (V/Q) lung scan and compression ultrasonography to detect deep venous thrombosis. This retrospective study analyzed the role of V/Q lung scan an...
متن کاملComparison of ultrasonography, computed tomography and 99mTc liver scan in diagnosis of Budd-Chiari syndrome.
Ultrasonography, computed tomography and 99mTc liver scanning are all useful in diagnosis of patients with the Budd-Chiari syndrome. In a study to determine their comparative value characteristic findings were recorded in all nine patients at ultrasonography and in seven patients at computed tomography. In contrast 99mTc liver scan showed a characteristic pattern in only one of eight patients. ...
