New Research Highlights Emerging MRI Contrast Agent for Bladder Imaging
A new MRI contrast agent may provide a viable non-invasive alternative for the detection of interstitial cystitis, according to preliminary research presented at the 5th International Consultation on Interstitial Cystitis Japan (ICICJ) in Kyoto, Japan.
Through intravesical contrast-enhanced MRI (ICE-MRI), the dual-component MRI contrast agent LP-20 facilitated enhanced phenotyping differentiation between bladder-centric interstitial cystitis (IC) and endometriosis, according to preliminary research presented at the 5th International Consultation on Interstitial Cystitis Japan (ICICJ) in Kyoto, Japan.
Researchers found that T1- and T2-weighted ICE-MRI images with LP-20 (Lipella Pharmaceuticals) enabled a wider field of view for pelvic abnormalities as well as visualization of sub-surface lesion depth and wall thickening on the serosal side of the bladder that one cannot see via cystoscopy.
The images reveal greater than 7 mm of bladder wall thickening and luminal side trabeculations for a 69-year-old patient with a urethelial lesion (A and C). A sagittal view for a 35-year-old patient revealed a bladder wall less than 5 mm in thickness. (Images courtesy of the 5th International Consultation on Interstitial Cystitis Japan (ICICJ)).
Designed for interstitial cystitis detection, the LP-20 agent may also facilitate the diagnosis of bladder pain syndrome (BPS), according to Lipella Pharmaceuticals.
“LP-20 provides a valuable tool for phenotyping IC/BPS, potentially streamlining patient identification for clinical trials and improving timely access to effective treatments,” added lead study author Pradeep Tyagi, M.D., an associate professor in the Department of Urology at the University of Pittsburgh Medical Center.
The company added that LP-20, which has been the subject of completed pre-clinical and proof-of-concept human trial research, can also diagnose the progression of bladder cancer to muscle invasive bladder cancer.

Could Ultrafast MRI Enhance Detection of Malignant Foci for Breast Cancer?
April 10th 2025In a new study involving over 120 women, nearly two-thirds of whom had a family history of breast cancer, ultrafast MRI findings revealed a 5 percent increase in malignancy risk for each second increase in the difference between lesion and background parenchymal enhancement (BPE) time to enhancement (TTE).
