Digital subtraction angiography in lower extremity phlebography

DSA was applied to the lower extremity phlebography on 21 cases (36 legs). The patient lay in the supine position and a tourniquet was placed around the ankle. Forty ml of contrast medium, diluted to 25% of the original concentration with normal saline, was injected into the dorsal vein of the foot. The anterior tibial vein, posterior tibial vein, peroneal vein and muscular vein of the calf were identified in 24 (63.2%), 36 (94.7%), 37 (97.4%) and 7 legs (18.4%), respectively. The poor opacification of the anterior tibial vein was attributed partly to the compression effect of the tourniquet. The abnormal findings were deep vein thrombosis (5 legs), reflux from the deep to the superficial vein (14 legs) and irregularity of the venous wall (16 legs). The superficial varicose veins were not demonstrated in DSA phlebography. The examination was comfortable because the patient position was supine and the dilute contrast medium caused no burning sensation. We believe that DSA phlebography is a safe and useful method for diagnosing the deep venous system disorders.     

Design of a birdcage array for lower extremity angiography

PURPOSE: To investigate the application of a coil array consisting of multiple birdcages for bolus chase magnetic resonance angiography (MRA) of the lower extremities. MATERIALS AND METHODS: The prototype consisted of four birdcage coils; two adjacent birdcages for thigh imaging, and two for calf imaging. Decoupling between adjacent coils was achieved using shared capacitors. Bench measurements and MR images were used to evaluate the decoupling scheme. Image signal-to-noise ratios (SNR) were compared between the birdcage array and four commercially available coils. Contrast-enhanced imaging experiments were performed on 10 volunteers and parallel imaging was simulated. This study was approved by the local institutional review board and written informed consent was obtained from each volunteer. RESULTS: Capacitive decoupling resulted in a reduction in signal leakage. The calf birdcages provided an 84% SNR improvement over a four element array, while the thigh birdcages provided a 53% improvement. Angiographic images illustrated the utility of the coil for peripheral MRA. Parallel imaging was demonstrated with a two-fold reduction factor. CONCLUSION: Birdcage coils were demonstrated to be valuable for lower extremity imaging due to their homogenous sensitivity, good SNR, and cylindrical geometry. Coupling was controlled using shared capacitors that allowed a single birdcage to encompass each leg individually, providing a novel approach to signal reception for peripheral imaging.     

Right atrial angiosarcoma and MRI: a case report

The authors report a case of right atrial angiosarcoma in a 29 year old man presenting with massive pericardial effusion. This case illustrates the value of MRI in the preoperative evaluation, providing accurate information about the site and extension of the tumor, and even about the malignant nature of the lesion. Multiplanar transesophageal echocardiography did not provide any additional information in this case.     

Primary cardiac angiosarcoma: a review and case report

Primary cardiac tumors, both benign and malignant, are rare. Approximately 25% of primary cardiac tumors are malignant, with the majority of these being sarcomas. One of the most common sarcomas is angiosarcoma. A case of primary angiosarcoma of the heart is presented which illustrates several of the features of this malignancy. The administration of systemic chemotherapy resulted in a brief stabilization of disease before progression and subsequent death occurred. Clinical signs and symptoms of cardiac tumors and diagnostic testing are discussed. Therapeutic options and efficacy of therapy are reviewed.
