DOI:
Objective: To evaluate the relationship between large vestibular aqueduct(LVA) and hearing loss, also obtain the threshold of LVA on coronal SCT of temporal bone. Methods: The SCT features of temporal bone from patients with enlarged vestibular aqueduct in the third affiliated hospital of Zhengzhou university were studied retrospectively. The midpoint diameter and width at the outlet of vestibular aqueduct were measured both on the axial and coronal SCT in normal individuals as well as in patients. The hearing tests from two different times were also performed to assess the evalution of hearing loss in patients with LVA. Results: In patients, the average midpoint diameter of the aqueduct was (2.4±0.93) mm and the average width of the aqueduct outlet was (6.21±1.4) mm on transverse view, the midpoint average diameter was (5.48±1.76) mm and the average width of the outlet was (6.87±1.61) mm on coronal view. The threshold value of the transverse diameter of the aqueduct for diagnosis of LVA was 2.5 mm, and the width of the outlet of the aqueduct was 4.25 mm on coronal view. There were no significant differences of both the air conduction and bone conduction from the two different times in patients, P>0.05. Follow-up study showed that 64.3% patients had mild to moderate hearing loss, only 2 cases had hearing improvement, 5 cases had hearing loss. There was no correlation of the vestibular aqueduct diameter with the bone conduction threshold value, while there was strong correlation between air conduction threshold and vestibular aqueduct diameter at low frequencies. Conclusion: Air conduction is the main factor in LVA patients with conductive or mixed hearing loss. SCT coronal scans can provide additional information to assess the LVA, especially when the axial scan diagnosis is insufficient.

DOI:
Objective: To investigate the feasibility of three-dimensional speckle tracking imaging(STI) for the assessment of left ventricular regional longitudinal systolic function of patients with different graded coronary artery stenosis. Materials and Methods: One hundred and ten patients suspected of coronary heart disease(CHD) in Beijing Hospital of the Ministry of Health were selected from June, 2010 to Aug, 2012. Men 68, women 42, average age was (63.2±8.9) years old. All patients received the examination of regular and three dimensional echocardiography before the CAG. The materials of the three dimensional all volume dynamic cardiac graph were collected and stored. The 3D dynamic graph using the 3D-STI offline were analyzed. The systolic peak longitudinal strain(LS) and the time of peak longitudinal strain(T-LS) of the 16 myocardial segments of the left ventricle(consist of 6 segments at the level of mitral orifice, 6 segments at the level of papillary muscles and 4 segments at apex section) were obtained. According to the results of the CAG, the subjects were divided into 5 groups: normal group(stenosis extent=0%), slightly narrowed group(0%＜stenosis extent≤25%), mild narrowed group(25%＜stenosis extent≤50%), moderate narrowed group(50%＜stenosis extent≤75%), severe narrowed group(stenosis extent＞75%). Using statistical software of SPSS 16.0 to compare the peak LS strain value and T-LS in different graded coronary artery stenosis. Results: In different grade coronary artery stenosis groups, LS of part of the myocardial segments corresponded to the lesion vessel were descending, while T-LS were ascending along with the increasing of the grade of setenosis, especially on the severe narrowed group. Conclusion: 3D-STI is feasible for the assessment of left ventricular regional longitudinal systolic function in patients with different graded coronary artery stenosis and can provide some supports for the diagnosis of CHD by noninvasive technique.

WANG Chuan-zhuo;LIU Zhao-yu
DOI:
Objective: To identify CT characteristics of primary pulmonary malignant fibrous histiocytoma(MFH). Materials and Methods: CT images and clinical data of 15 patients with primary pulmonary MFH proved pathologically were reviewed and analyzed retrospectively. Results: Among 15 patients, MFH appeared as peripheral lesions in 12 cases, located in left lobe 7 cases, right lobe 5 cases and central 3 cases. A total of 20 lesions were identified, in which 12 had single lesion and 3 had mutiple lesions, with mean a diameter of 8.5 cm and ranged between 3.5～15.4 cm, including 12 round-shaped and 8 mild lobulated lesions. Among all the 20 lesions, 14 were well-defined and the others had unclear border, while 5 masses were homogenous in density and the other 15 were inhomogenous with necrosis, cysts, bleeding or calcification. Twelve patients underwent enhanced CT, 17 lesions had various degress of enhancement in arterial phase and venous phase. Six lesions involved pleura and chest wall(among which 3 involved ribs), 1 involved pulmonary artery, 1 involved pulmonary vein, 2 involved pericardium, as well as 5 metastasis on pulmonary hilar or mediastinal lymph node, 4 distant metastasis. Conclusion: Primary pulmonary MFHs have some specific CT manifestations which are helpful to the diagnosis, but final diagnosis depends on the cytopathology and immunohistochemistry.

DOI:
Objective: To analyze percutaneous transhepatic cholangiography(PTC) imaging features of bile duct carcinoma thrombus. Materials and Methods: PTC images of 27 patients(the mean age was 49.81±7.27 years old) with histologically proved to have bile duct carcinoma thrombus were reviewed retrospectively. All 27 PTC were performed under the guidance of ultrasound or DSA by selective unilateral or bilateral intrahepatic bile duct puncture. Internal or external drainage was kept until repeated PTC was performed after 3~5 d to observe the imaging changes. Results: Filling defects in bile ducts were seen in all 27 patients. The filling defects and involved bile ducts showed expanding appearance in 26 cases. Proximal bile ducts to the involved parts were dilated like soft canes in 24 cases and fallen branches in 3 cases. Distal bile ducts showed no dilation in any of the case. The contours of filling defects were clearly shown in 9 cases and partially shown in 18 cases. Twenty-one cases showed constant filling defects while 6 cases had shrunken filling defects after drainage. Three types were defined according to the involved range: Type Ⅰ, 2 case; Type Ⅱ, 22 cases; Type Ⅲ, 3 cases. Conclusion: Bile duct tumor thrombus have some typical PTC imaging features, PTC is useful in detecting and diagnosing bile duct tumor thrombus.
