The maturity of quadriceps tendon with bone block was better in comparison with hamstring 6 months after anatomic SB ACL reconstruction. This study is clinically relevant in that modifying the individual rehabilitation according to the extent of graft maturity may be necessary to optimize patient function and prevent re-injury of the ACL graft.

ERSCMRI produced greater overall accuracy in staging for rectal carcinoma than did EUS.

There is a significant association between an ACL tear and increased patellar tendon length with a greater Insall-Salvati ratio. The mechanism for this finding is unclear, but this association provides support to suggest relative patella alta may be a risk factor for ACL injuries in pediatric patients.

Carotid artery dissection is a cause of stroke, especially in young and middle-aged patients. A dissection occurs when there is an intimal tear or rupture of the vasa vasorum, leading to an intramural hematoma, which is thought to result from trauma or can occur spontaneously, and is likely multifactorial, involving environmental and intrinsic factors. The clinical diagnosis of carotid artery dissection can be challenging, with common presentations including pain, partial Horner syndrome, cranial nerve palsies, or cerebral ischemia. With the use of noninvasive imaging, including magnetic resonance and computed tomography angiography, the diagnosis of carotid dissection has increased in frequency. Treatment options include thrombolysis, antiplatelet or anticoagulation therapy, endovascular or surgical interventions. The choice of appropriate therapy remains controversial as most carotid dissections heal on their own and there are no randomized trials to compare treatment options.

A prospective study was undertaken to determine the variability of hepatic vein Doppler waveforms in normal subjects. Seventy-five patients without liver or heart disease underwent Doppler examination of the middle hepatic vein. Normal triphasic tracings were observed in 68 subjects, while flattened tracings were observed in seven subjects. In addition, in four T he normal velocity curve of the hepatic vein reflects cardiac and respiratory events.t-J A triphasic pattern has been described in normal subjects, while flattening of this curve has been observed in cirrhotic patients and with the Valsalva maneuver.t--' !1 We conducted a study to determine if "abnormal" or flattened hepatic vein tracings are observed in healthy subjects. The effect of prolonged inspiration on the Doppler tracing was also studied. MATERIALS AND METHODSThe study group consisted of 75 subjects (age, 20-65 years; mean, 43 years) without liver or heart disease. All patients were examined with color flow images and pulsed Doppler tracings. Examinations were performed on a Quad 2000 (Siemens Quantum, Issa· quah, WA) or an ATL UM·9 (ATL,
