![]() However, in cases where ultrasound identifies a partial rupture, the authors suggest that a CT scan may be advisable. Doppler ultrasound will in all likelihood continue to be the initial imaging examination. The length of the distal stump measured in a CT image had a 96% correlation with the actual measurement taken during surgery.Īn acute Achilles tendon rupture is the most common tendon injury of the lower leg. CT identified all cases as a complete rupture. Doppler ultrasound identified 32 cases as a complete Achilles tendon rupture and four cases as a partial rupture. ![]() Thirty-three cases were diagnosed with a physical examination alone using the Thompson’s sign test. Lead author Hai-Peng Xue, MD, and colleagues reported that by observing the continuity and tension of the Achilles tendon in 3DVR and MPR, they could make a CT diagnosis. Multiplanar reconstruction (MPR) was used to adjust the angle of the access to obtain axial, sagittal, and coronal images of the achilles tendon. The CT images were post-processed using 3D volume reconstruction (VR) to create a 3D image of the tendon and bone after hiding the skin and fat based on the Hounsfield unit values. The study group included 36 patients diagnosed with complete Achilles tendon rupture who had both imaging examinations. Physicians from the Department of Orthopedics of the General Hospital of Shenyang Military Area Command of Chinese PLA in Shenyang, Liaoning conducted a 26-month long study to compare ultrasound and CT. Although ultrasound is usually performed in conjunction with a physical examination because of its availability, low cost, and ease of use, ultrasound may make a complete rupture appear to be a partial rupture, leading to an incorrect diagnosis, the study concludes. CT more accurately diagnoses a complete rupture of the Achilles tendon than does color Doppler ultrasound, according to a study from China published in Biomed Research International. ![]()
