El-din, S. E., A. A. Youssef, L. I. A. Metwally, A. A. Youssof, and H. A. El-Kiki, "The value of b0 images obtained from diffusion-weighted echo planar sequences for the detection of intracranial hemorrhage compared with GRE sequence", ejrnm, vol. 44, issue 4, 2013. Abstract

Purpose Our aim was to evaluate the clinical utility of b0EPI images obtained from diffusion sequence for the detection of the intracranial hemorrhagic lesions, especially acute
intracerebral bleeds thereby shorten the scan time particularly in the critical acute cases of stroke. Materials and methods Among all consecutive MR brain studies performed in our
department last year, we retrospectively selected those who followed the following criteria: (1) clinically suspected or radiographically confirmed acute infarction or hemorrhage. (2)
MRI imaging including DWI and T2∗ images. Sensitivity of hemorrhage detection, conspicuity of lesions, and diagnostic certainty were compared between the b0EPI and GRE sequences.
Results There were 77 hemorrhagic lesions with a variety of pathogeneses in various locations. 76/77 (98.7%) of these lesions were hemorrhagic (hypointense) on the GRE sequences,
whereas 61 (79.2%) were characterized as hemorrhagic on b0EPI images, and 16 (20.8%) were not detected. The overall difference in hemorrhage conspicuity/diagnostic certainty between
GRE and b0EPI sequences was statistically significant (P<.05). Conclusion b0EPI sequence, although shorter in acquisition time, was inferior to GRE imaging in the detection of acute and
chronic intracerebral hemorrhage. Keywords: Intracranial hemorrhage, Magnetic resonance, b0EPI, T2∗GRE

Ramadan, "Value of duplex Doppler ultrasonography in non-invasive assessment of children with chronic liver disease.", World journal of gastroenterology : WJG, vol. 16, issue 48, pp. 6139-44, 2010 Dec 28. Abstract

AIM: to investigate the value of duplex Doppler ultrasonography (US) in the assessment of the hemodynamics of the portal and hepatic veins in a cohort of children with chronic liver disease (CLD) and to detect any relationship between the US changes, etiology and severity (or stage) of CLD.

METHODS: we prospectively enrolled 25 children with biopsy-proven CLD. Thirteen had cirrhosis (aged 8.9 ± 2.0 years) and 12 had chronic hepatitis (aged 9.3 ± 2.3 years). Gray scale and color-coded duplex Doppler US were performed for all, as well as 30 healthy age and sex-matched controls. Findings were correlated with clinical, laboratory and histopathological characteristics.

RESULTS: prominent caudate lobe was detected in 100% of cirrhotics, but none of the chronic hepatitis or controls. Thickened lesser omentum and loss of the triphasic waveform of the hepatic vein were present in 69.2% and 53.8% of cirrhotics vs 33.3% and 8.3% of chronic hepatitis respectively. Portal vein flow velocity was significantly lower (P < 0.0001) and the congestion index was significantly higher (P < 0.005) in both patient groups compared to controls. Child-Pugh's staging showed a positive correlation with both abnormal hepatic vein waveform and direction of portal blood flow; and a negative correlation with both hepatic and portal vein flow velocities. No correlation with the etiology of CLD could be detected.

CONCLUSION: duplex Doppler added to grayscale US can detect significant morphologic and portal hemodynamic changes that correlate with the severity (stage) of CLD, but not with etiology.

Abstract

BACKGROUND: Management of acute limb ischemia (ALI) is largely based on the etiology of arterial occlusion (embolic vs. thrombotic). To our knowledge, the ability of duplex scanning to differentiate embolic from thrombotic occlusion has not been previously reported.

PURPOSE: To determine the ability of duplex scanning to differentiate embolic from thrombotic acute arterial occlusion.

METHODS: We prospectively recruited 97 patients (50.3 ± 19.7 years; 55% males) with 107 nontraumatic ALI in native arteries. All patients underwent surgical revascularization. Preoperative duplex scan detected arterial occlusion in the following arteries: iliac (11), femoral (38), popliteal (38), infrapopliteal (3), subclavian (3), axillary (1), brachial (9), and forearm arteries (4). We measured the arterial diameters at the site of occlusion (d(occl)) and at the corresponding contralateral healthy side (d(CONTRA)). The difference (Δ) between the two diameters was calculated as d(OCCL)-d(CONTRA). Duplex scan was also used to assess the state of the arterial wall whether healthy or atherosclerotic and the presence of calcification or collaterals. According to surgical findings, limbs were classified into embolic (E group=55 limbs) and thrombotic (T group=52 limbs) groups.

RESULTS: Both groups were comparable regarding age, diabetes, hypertension, smoking, atrial fibrillation, and time of presentation. The status of arterial wall at the site of occlusion and presence of calcification or collaterals were all similar in both groups. Δ in the E group was 0.95 ± 0.92 mm vs. -0.13 ± 1.02 mm in the T group (P<.001). A value of ≥ 0.5 mm for Δ had 85% sensitivity and 76% specificity for the diagnosis of embolic occlusion (CI 0.72-0.90, P<.001), whereas a value of less than -0.5 mm for Δ had 85% sensitivity and 76% specificity for thrombotic occlusion (CI 0.72-0.90, P<.001).

CONCLUSION: In acute arterial occlusion, ≥ 0.5 mm dilatation or diminution in the occluded artery diameter is a useful duplex sign for diagnosing embolic or thrombotic occlusion, respectively.
