Background: The increased use of imaging modalities has led to a greater incidence in depicting solid renal mass. These lesions comprise a wide spectrum of malignant such as renal cell carcinoma (RCC) and benign histologies. Objective: To determine the multidetector computed tomography (MDCT) features that discriminate RCC from other focal renal lesions. Methods: A retrospective review was performed on 148 patients who underwent renal CT scan followed by renal surgery or biopsy during January 2008 to July 2014. Specific predictive MDCT features of RCC were determined by logistic regression analysis. Interobserver agreement (kappa [K] values) was also calculated for each CT feature. Results: In 148 pathologic proved focal renal lesions, 91 (61.5%) were RCCs and 57 (38.5%) were non-RCCs. RCCs were more likely to be in male patients (OR, 5.39; 95% CI, 2.25 - 12.90), no internal fat component (OR, 46.50; 95% CI, 5.25 - 411.90), locate at peripheral (OR, 7.41; 95% CI, 1.63 - 33.73), and mixed central-peripheral locations (OR, 26.22; 95% CI, 4.23 - 162.58) of the kidney. There was moderate-to-excellent agreement among the readers over all these features (K = 0.43 - 0.91). Conclusions: Focal renal lesion with no internal fat component in MDCT is the most useful characteristic in differentiating RCCs from others.

We have developed a new X-ray microscope which produces complete three dimensional images of samples. The microscope operates by performing X-ray tomography with unprecedented resolution. Tomography is a non-invasive imaging technique that creates maps of the internal structure of samples from measurement of the attenuation of penetrating radiation. As conventionally practiced in medical Computed Tomography (CT), radiologists produce maps of bone and tissue structure in several planar sections that reveal features with 1mm resolution and 1% contrast. Microtomography extends the capability of CT in several ways. First, the resolution which approaches one micron, is one thousand times higher than that of the medical CT. Second, our approach acquires and analyses the data in a panoramic imaging format that directly produces three-dimensional maps in a series of contiguous stacked planes. Typical maps available today consist of three hundred planar sections each containing 512x512 pixels. Finally, and perhaps of most import scientifically, microtomography using a synchrotron X-ray source, allows us to generate maps of individual element.
