Abstract

We present a controlled image smoothing and enhancement method based on a curvature flow interpretation of the geometric heat equation. Compared to existing techniques, the model has several distinct advantages. (i) It contains just one enhancement parameter. (ii) The scheme naturally inherits a stopping criterion from the image; continued application of the scheme produces no further change. (iii) The method is one of the fastest possible schemes based on a curvature-controlled approach.

Contrast-enhanced magnetic resonance angiography MoBI-trak in the study of peripheral vascular disease.

PURPOSE: To evaluate the diagnostic accuracy of contrast-enhanced magnetic resonance angiography (CE-MRA) MoBI-trak of peripheral vessels in patients with peripheral vascular disease who were candidates for digital subtraction angiography (DSA). METHODS: Eleven patients underwent CE-MRA with automated table movement (MoBI-trak) using a 1.5 T superconducting magnet (Philips Gyroscan ACS NT) equipped with a Power Trak 6000 gradient. Contrast medium (Gd-DTPA) was administered in two sequential boluses-20 cm(3) at 0.6 cm(3)/sec (starting phase) and 20 cm(3) at 0.3 cm(3)/sec (maintenance phase)-using a MedRad Spectris automatic injector. DSA was the gold standard and was performed using a Philips Integris 3000, with a brilliance intensifier of 38 seconds. DSA and MRA were evaluated on printed films. RESULTS: DSA provided 213 diagnostic assessments: 144 negative, 30 stenosis <50%, 5 stenoses in the 51-70% range, 12 stenoses in the 71-99% range and 22 occlusions. CE-MRA MoBI-trak sensitivity, specificity, positive and negative predictive value and diagnostic accuracy were 94.1%, 99.2%, 98.4%, 80.0% and 97.5%, respectively. CONCLUSIONS: Our work is in accordance with the literature. Using this technique MoBI-trak has been shown to be a reliable technique for the detection of peripheral vascular disease up to the trifurcation, although it underlines the necessity for more diagnostic investigation and improvements in the technique.

Gadodiamide as an alternative contrast agent in intravenous digital subtraction angiography and interventional procedures of the upper extremity veins.

PURPOSE: Patients with renal insufficiency or other contraindications to iodine-based contrast agents present a significant management dilemma when angiography or interventional procedures are required. We describe the use of gadolinium as an alternative contrast agent for intravenous digital subtraction angiography (IV-DSA) and interventional procedures of the upper extremity veins. METHODS: Sixteen patients with symptoms of with moderate renal insufficiency underwent digital subtraction angiography for upper extremity and subclavian venography. Angiographic studies were obtained using gadolinium as a contrast agent. In six patients we used stents. RESULTS: Diagnostic images were obtained in all cases. No patient suffered a complication related to the use of gadolinium, and no patient demonstrated worsened renal function after the procedure. CONCLUSION: In the setting of a contraindication to iodine-based contrast agents, gadolinium represents an important alternative contrast material that allows for the visualization of and interventional procedures in the upper extremity veins.

Bilateral paramedian thalamic infarct in the presence of an unpaired thalamic perforating artery.

Bilateral paramedian thalamic infarction is rare. The suggested mechanism is occlusion of a central unpaired thalamic perforating artery--an anatomic variant. In the few existing reports of this condition, the diagnosis was based on computed tomography (CT) or magnetic resonance imaging (MRI) findings alone. Other causes of thalamic lesions were not ruled out, and there was no angiographic demonstration of the presumed variant artery. We present a case of a 48-year-old man with a bilateral thalamic infarction seen on CT and MRI. Initial neurological examination revealed lethargy, severe combined motor and sensory aphasia, and a mild upward gaze limitation. The patient had no focal motor deficits. After 24 hours, the patient was more alert and his speech became more fluent, but Korsakoff-type amnesia with poor attention span became apparent. The patient improved slowly over 6 months of rehabilitation. Bilateral thalamic lesions can be caused by several conditions. Among those are thiamine deficiency, cerebral lupus, toxoplasmosis, cysticercosis, cerebral syphilitic gumma, and even tumors and fungal infections. All these were ruled out in our case. Superselective digital subtraction angiography (DSA) demonstrated a single unpaired thalamic perforator. To our knowledge, this is the first time this anatomical variant has been demonstrated in vivo in association with bilateral thalamic infarction.
