Renal cell carcinoma in patients with acquired cystic disease of the kidney: Assessment using a combination of T2‐weighted, diffusion‐weighted, and chemical‐shift MRI without the use of contrast material

Abstract

The MRI findings, including findings on DWIs and CSIs, well reflected the histopathologic findings of RCC in patients with ACDK.

Towards the identification of multi-parametric quantitative MRI biomarkers in lupus nephritis

“…The total duration for the multi-parametric renal qMRI protocol including structural MRI scans was 30-40 min. There are alternative MRI techniques which were not included in our protocol, such as chemical-shift imaging [34] that are not directly related to renal function and MR spectroscopy [35], for which the duration of acquisition may be prohibitive. There are several limitations of the present study: 1) both ASL and T1rho MRI were single-slice.…”

Inter-observer variation and diagnostic efficacy of apparent diffusion coefficient (ADC) measurements obtained by diffusion-weighted imaging (DWI) in small renal masses

“…This fact could be used for development of computerassisted applications identifying and differentiating small renal masses in a quantitative and automated manner. Prior research on ADC values identified differences between renal lesion subtypes (Table 4) (11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27). Although data on benign lesions are very heterogeneous due to different inclusion criteria between studies including or excluding Bosniak I and II cysts, several researchers have demonstrated significant differences between renal cell carcinoma subtypes (Table 4).…”

Renal Cell Carcinoma in End-Stage Renal Disease

“…2). Akita et al [14] reported 10 RCCs containing viable parts in the pathologic specimens showed high signal areas on DWI (at high b values). Solitary RCC with no macroscopic degeneration was visualized as a homogenous high SI on DWI and as a homogenous iso SI on T2-weighted image (T2WI).…”

“…Ultrasonography (US), one of standard screening tools of RCC in dialysis patients, sometimes fails to distinguish RCC from hemorrhagic cysts [13]. The usefulness of magnetic resonance imaging (MRI) without the use of contrast material has been reported for the detection of RCC in patients with ACDK [14]. The principle treatment strategy for RCC in dialysis patients is radical nephrectomy (RN).…”
