PURPOSE: The purpose of this study is to describe the findings of the transligamnetous type of the herniated lumbar disc (HLD) with magnetic resonance MR imaging. MATERIALS AND METHODS: We retrospectively analyzed the MR images of surgically proven 20 cases of transligamentous type of HLD from January 1, 1992 to August 20, 1992. The MR imaging was performed with 1. 0T MR unit, using sagittal spin echo (SE) and axial gradient echo (GE) techniques. RESULTS: The results were as follows;1) the interruption of black line of the posterior longitudinal ligament (PLL) was identified in 19 levels and 17 levels in sagittal SE and axial GE images, retrospectively;2) the widening of adjacent epidural fat space was demonstrated in 16 cases of central or posterolateral HLD. The herniated disc material, as compared with the parent intervertebral disc, showed intermediate signal intensity (SI) in 19 and low SI in 1 level on T1WI, high SI in 10, intermediate SI in 7, low SI in levels on T2WI, and high SI in 10, intermediate SI in 9, low SI in 1 level on GE images. CONCLUSION: The most important sign of the transligamentous type HLD on MRI was the interruption of the black line with additional finding of the widening of adjacent epidural fat space. The MR signal intensity of the herniated disc was variable. Axial GE image was valuable for the evaluation of the direction of HLD and it relationship with neural structure, but had no addiational information for the degree and biochemical change of HLD over SE image.

BACKGROUND: Cine MR imaging has been found to bo a non-invasive technique in evaluation cardiac anatomy and cardiovascular function in a variety of cardiac diseases. The capability of this technique for quantatively estimating the severity of regurgitation has not been tested in newborns. The purpose of this study is to compare the degees of tricuspid regurgitation by echorcardiography with those by cine MRI, and verify the utility of MRi in evaluating tricuspid regurgitation. METHODS: Fifty-one newborns with tricuspid regurgitation were evaluated on the same day by echocardiography and cine MRI. Area and regurgitant fraction of area were estimated at four chamber view by two techniques. RESULTS: The area of tricuspid regurgitation was similar by two techniques. The correlation for the area(r=0.66, p<0.025) and the regurgitant area fraction(r=0.647, p<0.025) of tricuspid regurgitation obained by cine MRI with echocardiographic data was good. CONCLUSION: Cine MR imaging can provide quantative data estimating for evaluation of tricuspid regurgitation in newborns.

Recently, duplex sonography has been used as a screening test for the evaluation of carotid arterial disease. If an occlusion of atherosclerosis is located at the bifurcation of the common carotid artery or the lower portion of the internal carotid artery, the luminal change may be directly visualized on high-resolution B-mode sonography or color-Doppler images. But when the lesion is located at the high cervical, petrous or cavernous protion of the internal carotid artery, it is difficult to directly visualize the lesion with the sonography. The purpose of this paper is to evaluate the indirect changes on the Doppler patterns of both common carotid arteries with clamping of an internal carotid artery. Thirty common carotid arteries in fifteen normal rabbits were examined with duplex ultrasonography using high-resolution real-time imaging and 7.5MHz pulsed-wave Doppler flow measurements with velocity waveform analysis. Systolic velocity (SV) was 45.4±8.4cm/sec, end-diastolic velocity (EDV) 15.3±4.9cm/sec and resistative index(RI) 0.66±0.08 in the common carotid artery before clamping of the internal carotid artery. SV was 26.3±7.8cm/sec, EDV 6.0±5.2cm/sec and RI 0.78±0.18 in the ipsilateral common carotid artery and SV was 56.6±13.0cm/sec, EDV 22.3±8.2cm. sec and RI 0.61±0.10 in the contralateral common carotid artery after clamping of the internal carotid artery. During clamping of the internal carotid artery, the difference between SV of bilateral common carotid arteries was 30.3±13.8cm/sec and EDV 16.3±9.2cm/sec. There was no difference of the velocity patterns of the common carotid artery between preclamping and declamping of the internal carotid artery. In conclusion, lower SV and EDV in a common carotid artery than that in contralateral side on Doppler patterns strongly suggests an occlusion of ipsilateral internal carotid artery.
