Throughout the last two decades, MRI has been ameliorated by a dramatic increase in the field strength; from 0.015 to 7 Tesla (T) MR systems. Ultrahigh-field MR system (beyond 3T) has great potential to produce newly improved imaging capabilities for both clinical diagnosis and basic science research. The primary purpose of venography was the description of cerebral veins, but it has also been ...

Background Multiple algorithms exist for treating acute primary upper extremity deep venous thrombosis (pUEDVT) caused by thoracic outlet syndrome (VTOS). In this case series, we present the results of our dedicated same admission treatment algorithm. Methods All patients between January 2015 and December 2019 with an established (symptoms <14 days) VTOS were treated according...

Deep venous thrombosis of the lower extremity poses a diagnostic challenge. Clinical signs and symptoms are often misleading, and sensitive and specific tests are essential for diagnosis. The cost, patient discomfort and risk of morbidity associated with contrast venography have led to the development of noninvasive diagnostic techniques such as Doppler ultrasound, impedance plethysmography and...

Fewer than 20 cases of adventitial cystic disease of the vein have been reported in the worldwide literature. This small number of reported cases may be due not only to the disease's low incidence, but also to the difficulty in making the proper diagnosis. Many techniques have been used to investigate this disease, but venography has been the traditional diagnostic tool. In this report we prese...

Impedance plethysmography using the cuff technique has been compared with venography in 346 consecutive patients with suspected venous thromboembolism. The limbs were classified according to the venographic results as no thrombosis, proximal (popliteal, femoral, or iliac) vein thrombosis, and calf thrombosis. A discriminant analysis was performed. The impedance plethysmographic result was norma...

Although it is generally accepted that negative venography excludes deep vein thrombosis (DVT) in patients in whom it is clinically suspected, there is no evidence to support this conclusion. To test the correctness of withholding anticoagulant therapy in these patients, we followed 160 consecutive patients who had clinically suspected DVT and negative venograms to determine the frequency of po...

in psychopathology, which worsened after a three-day washout period and became similar to that seen before metoclopramide treatment. The patient was then treated with the classical neuroleptic haloperidol. At a dose of 45 mg/day the same extrapyramidal syndrome re-emerged and was completely responsive to trihexyphenidyl 2 mg by mouth three times daily. After haloperidol dosage was increased to ...
