“…Diffusion-weighted imaging has proven to be a promising diagnostic imaging modality for genitourinary malignancies [18]. In renal tumors, apparent diffusion coefficient (ADC) values are lower for RCC compared to oncocytoma [19].…”

“…Most applications of ASL are in translational or preclinical research; however, some institutes use ASL measurements to assess perfusion in pediatric tumors without a need for contrast agent administration 139 . Owing to difficulties in finding adequate labeling planes, ASL is typically used in brain, head and neck, and renal tumors 140 – 143 , but has also been investigated in other organs, such as the liver 144 , heart 145 , and prostate 146 . The low resolution of ASL images with respect to that of conventional MR sequences limits its use in oncological screening; however, the benefit of avoiding contrast agent administration is expected to result in increased use of this technique in pediatric imaging, in oncological patients with many follow-up exams, and in oncological wards aiming to replace contrast-agent-based perfusion MRI with less expensive imaging.…”

This review is aimed at presenting some of the recent developments in translational cancer imaging research, with a focus on novel, recently established, or soon to be established cross-sectional imaging techniques for computed tomography (CT), magnetic resonance imaging (MRI), and positron-emission tomography (PET) imaging, including computational investigations based on machine-learning techniques.

“…Also, these methods can be useful to monitor tumor response to therapy quantitatively. 2 Parallel imaging and breath hold sequences in mpMRI can help to decrease examination time and increase image quality. A solid renal nodule shows raised T2 signal intensity (SI) and is characteristic of renal cell carcinoma (RCC); whereas hemorrhagic cyst and AML shows decreased T2SI.…”

Evaluation of renal space occupying lesions with multiparametric MRI and its correlation with histopathology findings- an observational study

The term multiparametric MRI, is a useful tool in reference to an approach that takes advantage of the added value of different MR imaging acquisitions to yield anatomic and pathophysiologic information about renal space occupying lesions and to evaluate patients with different tumors, including genitourinary malignancies. The role of multiparametric MRI is continuously growing because of its ability to detect and characterize renal space occupying lesions as well as to assess response to treatment. An observational study was carried out in 50 patients who presented with renal mass, based on clinical suspicion and prior imaging diagnosis of neoplastic renal space occupying lesion. Total renal space occupying lesions were 50, of which, 38 were males & 12 were females. The age range of the study population was 30–80 years. In our study, Agreement analysis between mpMRI diagnosis and HPE diagnosis of different RCC subtypes was statistically significant. So, multiparametric MRI had a role in differentiating the subtypes of RCC which had fair agreement with HPE. The present study results state that the renal mass lesions has different ADC values for different lesions because of the change in tissue contents and there was a statistically significant difference in ADC values between low and high-stage RCCs. Histologic and radiologic profiles of renal space occupying lesions and diverse subtypes of RCC can be used as biologic indicators of clinical behavior, response to treatment, and prognosis.
