Overview
Magnetic resonance imaging (MRI) is used in genitourinary tract conditions if CT scan is non-diagnostic or when CT scan is contraindicated. Diffusion-weighted MRI (DW-MRI) can differentiate pyonephrosis from hydronephrosis.
MRI
- Magnetic resonance imaging (MRI) is used in genitourinary tract conditions if CT scan is non-diagnostic or when CT scan is contraindicated.
- High soft tissue resolution and no radiation exposure are the advantages of MRI.[1]
- Diffusion-weighted MRI (DW-MRI) can differentiate pyonephrosis from hydronephrosis.[2]
- Pyonephrosis exhibits hyperintense signals in the collecting system (pus), whereas hydronephrosis demonstrates hypointense signals.
