PURPOSE: To evaluate the safety of withholding anticoagulation in @entity1 with suspected @entity1151 after negative multislice computed tomography (MSCT) pulmonary angiography and lower-limb venography. MATERIALS AND METHODS: A total of 383 consecutive @entity1 with suspected @entity1151 were prospectively studied. @entity1 underwent MSCT pulmonary angiography and lower-limb venography, as well as pulmonary scintigraphy and lower-limb ultrasound examination. @entity1 with negative MSCT results for both @entity1151 and @entity49 were not administered anticoagulants and were followed up for 6 months to rule out @entity1031 . RESULTS: At MSCT, 156 @entity1 were positive for @entity1151 , @entity49 , or both; 224 were negative; and findings were inconclusive in three. False-negatives were five @entity1 with high probability scintigram and two with @entity49 detected at US. A total of 184 @entity1 with negative MSCT and without anticoagulation were followed up for 6 months. During this period of time just one recurrence of @entity1151 was detected. The negative predictive value of MSCT pulmonary angiography plus lower-limb venography was 95.8% (183/191). CONCLUSION: MSCT is efficacious in diagnosing @entity1151 , with negative predictive values reported in the literature ranging from 94% to 100%. This enables omission of anticoagulation in @entity1 with suspected @entity1151 after negative MSCT findings without the need for other diagnostic tests.

Can multislice CT alone rule out reliably XXXX ? A prospective study.
