PURPOSE – The refractive index (RI) is a unique physical property of tissue. It changes in neoplastic and inflammatory condition of brain due to depletion of tissue glutathione concentration changing the electron density. The purpose of the study was to predict RI value of the brain lesions from the CT-MR fused images non invasively. MATERIALS AND METHODS –CTMR fusion image was produced by combining CT and MR images by rigid registration technique to detect the pathology accurately. Independent component analysis determines the color value and gray value of the images of the tissue. These values were then used by Neural Network software to generate a color mapping of the CT-MR fusion image. Electron density derived from CT images and optical frequency from color image were used to determine RI value by applying Feynman’s equation. RI value and glutathione levels of corresponding biopsy specimens were determined in the laboratory. RESULTS –.A colored CT-MR fusion image shows true color of the tissue. The RI values determined from images were in agreement with biopsy determined RI values. Values between 1.353 through 1.359 are benign and RI value above 1.412 were found malignant.CONCLUSIONPredicting RI value using colored CT-MR fused images will increase diagnostic accuracy.

PURPOSE:To produce an enhancement-like effect of the brain lesions of MRI images mathematically, without intravenous injection of contrast.INTRODUCTION:To improve the visibility of internal body structures, MRI contrast agents are used. Gadolinium (Gd), a paramagnetic substance, is the most commonly used compound for contrast enhancement. Gd is introduced into the blood stream for enhancement of brain tumors and various lesions depending upon the degradation of the blood-brain barrier. Due to their hydrophilic character, gadolinium chelates do not pass the blood-brain barrier. Contrast (Gd) mediated nephropathy (CMN) and systemic fibrosis are two notorious, irreversible complications.MATERIALS AND METHODS: A multi-slice EPI IR sequence was used to assess T1 relaxation times of various brain lesions and brain tumors before and after administration of gadolinium. T1 relaxation time and signal intensity with corresponding gray scale values (out of 256 shades) of various brain lesions before and after IV contrast were tabulated. A statistical relationship was determined for the magnitude of changes in the T1 values of brain tumors before and after the contrast material was added. Enhancement-like effects of the lesions could be reproduced mathematically with the help of neural networks without the IV contrast injection. With the help of Kmean clustering, the data were classified. A mapping function was generated that corresponded between these independent components and the cross-sectional data by using the neural network after training the network with a sample dataset. The training sample for the network was selected using K-mean clustering. A mapping of the lesion was done overlaid on the T1 weighted image.CONCLUSION: An attempt was successfully made to enhance various brain lesions statistically utilizing neural networks and without using IV contrast.

There is a growing interest in understanding recruitment, retention, and turnover of allied health professionals in consideration of employment trends and workforce mobility, an increased need to understand the healthcare delivery system and the dynamic nature of the allied health workforce, especially for rural areas. A survey was sent to allied health administrators across a variety of allied health disciplines from the state of Tennessee hospitals in order to gauge opinions on retention and recruitment strategies. Overall, successful strategies for recruitment and retention of radiography professionals were reported, as well as, differences between urban and rural areas, differences among allied health disciplines, perceptions of strategy effectiveness, and key strategies for rural allied health recruitment.

Aim: To compare the diagnostic performance of Gd-DOTA-enhanced MRI with non-enhanced MRI in the characterization of tumoral lesions with histological (or other) corroboration.Materials and Methods: Pooled data included 381 patients from three comparable Phase III trials of patients with abdomino-pelvic, hepatic and cerebro-spinal lesions. Each patient underwent MRI with appropriate unenhanced sequences (pre), followed by an injection of Gd-DOTA (0.1 mmol/kg) and corresponding enhanced sequences (post). Histology was used as the gold standard or, in the hepatic study, a corroborative diagnosis. Qualitative and quantitative assessments of images were done by one on-site and two independent off-site blinded readers.Results: Technical failures were at least five times more frequent on the unenhanced sequences compared with the GdDOTA-enhanced sequences. Delineation of lesion borders was superior with enhanced MRI compared with unenhanced MRI, irrespective of evaluation off-site (‘post’-injection/‘pre+post’-injection: 60.9%/65.3% versus ‘pre’-injection: 35.5%, p<.0001) or onsite (post: 75.8%, versus pre: 39.9%, p<.0001). Gd-DOTA sequences improved diagnostic confidence both off-site (76.2%/83.2% versus pre: 57.6%, p<.0001) and on-site (88.7%/93.9% versus pre: 43.9%, p<.0001). Sensitivity and specificity were statistically significantly improved with Gd-DOTA for off-site (pre+post/post: 90.3%/88.8% versus pre 84.3%; and 71.1%/76.2% versus 65.3%) and on-site (95.2%/94.7% versus 71.2% and 81.9%/81.0% versus 60.8%) readings, respectively. There were no unexpected adverse events.Conclusion: Gd-DOTA-enhanced MRI resulted in fewer technical failures, better image quality and better diagnostic performance compared with unenhanced MRI, confirming that Gd-DOTA adds clinical value and greater diagnostic confidence to the characterization of tumoral lesions.

Intrahepatic pancreatic pseudocyst is a very rare differential for a hepatic space occupying cystic lesion. Though pseudocysts complicating chronic calcific pancreatitis are well described , an isolated intrahepatic location is extremely rare. Moreover , Intrahepatic pancreatic pseudocysts are usually described following acute pancreatitis. In this case report we describe the case of a 60 year old male presenting with epigastric pain and abdominal distension, in whom computed tomography showed features of an intrahepatic pancreatic pseudocyst complicating chronic calcific pancreatitis, which was subsequently confirmed on surgery. The etiopathogenesis and the types of intrahepatic pancreatic pseudocysts are discussed in addition to describing the imaging differentials.

PURPOSE: Refractive index (RI) is unique in discriminating various tissues. It is dependent on water and solid components such as protein and phospholipid of brain tissue resembling hydrogel. Our purpose was to determine RI of normal and pathological tissues of brain from the MR T2 relaxation time (T2 value) to determine relative water and solid contents of a tissue and discriminate various pathological lesions by the help of RI in T2 weighted MR images.METHODS: In a 0.3 Tesla permanent and 3 Tesla superconductor magnets T2 maps were created along with T2 shades to get T2 value of various brain tissue homogenates prepared from biopsy samples of known RI using multi-echo datasets by a read out train. T2 value of CSF, gray/white matter and various pathological lesions were determined.From the relationship of RI and T2, a RI map of brain and RI shade were produced. Computer generated RI and color coded map of T2 weighted images of various lesions were created. RESULTS: Analyzing various RI of pathological lesions it was noted that, RI of malignant lesions were more than 1.421 whereas RI of benign lesions were less than 1.395CONCLUSION: RI and color coded map may discriminate between benign and malignant lesions of brain.
