Comparison of duplex ultrasonography and venography in the diagnosis of deep venous thrombosis.
Sixty-five patients with suspected deep venous thrombosis (DVT) in 68 limbs were entered consecutively into a study to compare venography with duplex ultrasonography scanning. Both tests were performed on 64 limbs, venography being contraindicated in four. Overall, duplex scanning correctly identified 86 per cent of DVTs diagnosed on venography and correctly excluded 80 per cent with negative v...
متن کاملRadionuclide plethysmography and Tc-99m red blood cell venography in venous thrombosis: comparison with contrast venography.
Radionuclide plethysmography (RPG) is a new technique that uses Tc-99m labelled red blood cells to ascertain changes in venous volumes by detecting the change in counts in response to the inflation and deflation of proximal thigh cuffs. Diagnosis of ileofemoral venous occlusion is possible using this technique, which also provides kinetic data of venous outflow. A range of normal values was def...
متن کاملDiagnosis of deep venous thrombosis. A prospective study comparing duplex scanning to contrast venography.
Duplex scanning has been proposed as a safe alternative to contrast venography for diagnosing deep venous thrombosis, but its accuracy has not been proved. In this prospective, double-blind study of 47 patients, the sensitivity and specificity of duplex scan criteria were determined relative to contrast venography for lower extremity deep venous thrombosis. Criteria considered to show the prese...
متن کاملMagnetic resonance venography of intracranial venous diseases.
289 Over the past decade, neurologists and neuroradiolo-gists have paid increasing attention to the role of the intracranial venous system in cerebrovascular diseases, such as dural sinus steno-occlusive diseases. The intra-cranial venous system has been evaluated traditionally during the venous phase of conventional catheter digital subtraction angiography (DSA). In fact, DSA is still the gold...
متن کاملPattern of magnetic resonance imaging and magnetic resonance venography changes in cerebral venous sinus thrombosis.
BACKGROUND Cerebral venous sinus thrombosis is a common but highly under-recognised condition, which is missed not only by general practitioners but also by neurologists. Computerised tomography (CT) or magnetic resonance imaging (MRI) of brain alone is not sufficient to diagnose this condition. Objective of this study was to explore the pattern of magnetic resonance imaging (MRI) and magnetic ...
