The Cerebral Palsy Research Registry was created to fill the gap between population and clinical-based cerebral palsy registries and promote research in the field. This is accomplished by connecting persons with cerebral palsy, as well as their families, to a network of regional researchers. This article describes the development of an expandable cerebral palsy research registry, its current status, and the potential it has to affect families and persons with cerebral palsy in the United States and abroad.”
“Purpose: To assess the usefulness of apparent diffusion coefficients (ADCs) for characterizing renal

cell carcinoma (RCC) sub-types at 3.0 GSK1838705A Protein Tyrosine Kinase inhibitor T.

Materials and Methods: The Institutional Review Board approved this retrospective study, and informed consent was waived. Eighty-three patients underwent diffusion-weighted (DW) magnetic resonance (MR) imaging of 85 renal masses. In each patient, precontrast

single-shot spin-echo echo-planar DW imaging was performed with b values of 0 and 500 and 0 and 800 sec/mm(2) by using a 3.0-T MR imaging system. Differences in ADCs between the RCC lesions and uninvolved renal parenchyma were tested by using a paired-samples t test. One-way analysis of variance was used to compare ADCs of the various RCC subtypes. Receiver operating characteristic (ROC) curve analysis was used to selleckchem test the ability of ADCs in differentiating clear cell from non-clear cell RCCs.

Results: Pathologic diagnoses of the 85 tumors (median diameter, 4.4 cm) in the 83 patients

(54 men, 29 women; age range, 23-75 years; mean age, 49.4 years) were clear cell RCC for 49 tumors, papillary RCC for 22 tumors, and chromophobic RCC for 14 tumors. With Selleckchem GDC-0449 b values of 0 and 500 sec/mm(2), clear cell RCCs showed a significantly higher mean ADC (1.849 x 10(-3) mm(2)/sec) than papillary (1.087 x 10(-3) mm(2)/sec) and chromophobic (1.307 x 10(-3) mm(2)/sec) RCCs (P<.001); however, the difference between papillary and chromophobic RCCs was not significant (P =.068). With b values of 0 and 800 sec/mm(2), clear cell RCC showed the largest mean ADC (1.698 x 10(-3) mm(2)/sec) of the three subtypes, and the difference between each pair of subtypes was significant (P<.001). ADCs obtained with b values of 0 and 800 sec/mm(2) were more effective for distinguishing clear cell from non-clear cell RCC (area under the ROC curve, 0.973): A threshold value of 1.281 x 10(-3) mm(2)/sec permitted distinction with high sensitivity (95.9%) and specificity (94.4%).

Conclusion: DW imaging with b values of 0 and 800 sec/mm(2) allows sensitive and specific differentiation of clear cell, papillary, and chromophobic RCCs, suggesting that DW imaging may be useful in the preoperative characterization of RCC. (C) RSNA, 2010″
