Purpose: To evaluate the extent to which Tissue Harmonic Imaging (THI) and spatial averaging (Sono-CT, Cross Beam) facilitate the diagnosis of lower leg venous thrombosis. Materials and Methods: In 100 cases of lower leg venous thrombosis, the conventional Bscan, THI, and ultrasonic CT technology (Cross Beam) in examinations using a multi-frequency transducer head (9 - 14 MHz, Logiq 9, GE) were compared during follow-up studies using compression sonography over at least 6 weeks. Two independent examiners performed digital image documentation (PACS connection) without modifying the gray level parameters optimized in the B-scan. A thrombosis was considered to be proven sonographically if at least one ultrasonic modality yielded findings reproducible in follow-up checks at a comparable site in accordance with both examiners. Results: Thromboses in the V. tibialis posterior category (97%) and the fibular category (81%) were found most often, followed by muscular venous thromboses (48%). Thromboses in the V. tibialis anterior category were rare (12%). The procedure comparison showed an advantage for ultrasonic CT technology in terms of the demarcation of thromboses of the deeper veins (sensitivity 98%), as compared to THI (sensitivity 87%, specificity 91%, PPV: 99%) and the B-scan (sensitivity 81%). Conclusion: if a high-resolution linear transducer is used, THI and ultrasonic CT-Technology can facilitate the diagnosis of a lower leg venous thrombosis.
