OBJECTIVES To study the value of assessing renal masses using different methods in parameter approaches and to determine whether BOLD MRI is helpful in differentiating RCC from benign renal masses, differentiating clear-cell RCC from renal masses other than clear-cell RCC and determining the tumour grade. METHODS Ninety-five patients with 139 renal masses (93 malignant and 46 benign) who unde...

ID: 6000 Title: MRI Relaxometry BMD Measurements using Conventional Phase Symmetrized Rapid Increased Flip Spin Echo and Standard Gradient Echo and its correlation with DXA Purpose: Recently, several special MRI protocols have been developed for BMD measurements for deriving R2(=1/T2), R2*(=1/T2*) and R2'(=R2*-R2) applied in several cross sectional studies. But, due to high slew rate gradients ...

For simplicity, we adopt the following convention: x, x0, y, y0, r are real numbers, z, z0 are elements of R2, f , f1, f2 are partial functions from R2 to R, R is a rest, and L is a linear function. Let us note that every rest is total. Let f be a partial function from R2 to R and let z be an element of R2. The functor pdiff1(f, z) yielding a function from R2 into R is defined as follows: (Def....

R2 non-LTR retrotransposons exclusively insert into the 28S rRNA genes of their host, and are expressed by co-transcription with the rDNA unit. The grasshopper Eyprepocnemis plorans contains transcribed rDNA clusters on most of its A chromosomes, as well as non-transcribed rDNA clusters on the parasitic B chromosomes found in many populations. Here the structure of the E. plorans R2 element, it...

This study was conducted to assess the ability of the VCS2001 (E+V, Oranienburg, Germany) video image analysis system to predict pork carcass composition. Pork carcasses (n = 278) were selected from a commercial packing plant to differ in weight, Fat-O-Meater (FOM) predicted percentage lean, and gender. Carcasses were imaged three times with the VCS2001, chilled overnight, and then sequentially...

Introduction: Transverse relaxation rates, R2 and R2* and the apparent diffusion coefficient (ADC) are all typically estimated from the exponential decay of MR signal magnitude as a function of either echo time (for R2 and R2*) or b-value (for ADC). Changes in R2 and R2* induced by ultrasmall paramagnetic iron oxide (USPIO) contrast agents, along with ADC, have recently been utilised to estimat...
