Magnetic resonance imaging
Ans. is 'a' i.e., Intravenous Urography Intravenous urography or pyelography (I VU or I VP) is the most sensitive modality to detect early renal tuberculosis. In the early stages it shows irregularity or destruction of one or more renal papillae.For ultrasound, Campbell writes- "Ultrasonography is of limited value in the initial investigation of the genitourinary TB."For CT, Campbell writes - "CT is of limited value in the early investigation of genitourinary TB because intravenous urography gives such accurate pictures".For MRI, Campbell writes - "MRI has very little application in the management of genitourinary TB"
