Imaging Studies I: Kidney, Ureter, and Bladder Studies

Imaging Studies I: Kidney, Ureter, and Bladder Studies

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

Imaging Studies IV: Magnetic Resonance Imaging

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Imaging Studies VI: Voiding Cystourethrography and Cystography

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

Summary

Diffusion kurtosis imaging reveals white matter changes in overactive bladder syndrome (OAB). Altered microstructural parameters like kurtosis fractional anisotropy (KFA) may serve as diagnostic biomarkers for OAB.

Background:

Overactive bladder syndrome (OAB) is a condition affecting bladder function.
The underlying white matter (WM) microstructural changes in OAB are not fully understood.

Purpose of the Study:

To investigate WM microstructural alterations in OAB patients using diffusion kurtosis imaging (DKI).
To explore the diagnostic potential of DKI-derived parameters in OAB.

Main Methods:

Prospective study comparing 30 OAB patients with 30 healthy controls (HC).
Tract-based spatial statistics (TBSS) applied to DKI data to assess WM parameters (KFA, FA, MK, MD).
Correlation analysis between DKI parameters and OAB Symptom Score (OABSS); ROC curve analysis for diagnostic performance.

Main Results:

OAB patients showed significantly decreased KFA and FA compared to HC.
OAB patients exhibited significantly increased MK and MD compared to HC.
KFA in the genu of corpus callosum and FA in the anterior corona radiata correlated with OABSS scores. KFA demonstrated superior diagnostic performance.

Conclusions:

DKI is a valuable tool for investigating OAB pathophysiology.
DKI-derived parameters show potential as biomarkers for OAB clinical diagnosis.
