Infectious foci found by wb-MRI in patients with FUO. Axial contrast enhanced T1-VIBE image of a 81-year old-patient a shows gallbladder wall thickening, contrast enhancement and lithiasis as signs of subacute cholecystitis which had eluded diagnosis by abdominal ultrasound. In another patient, an 88-year-old female, b the contrast enhanced T1-VIBE displays a perifemoral intramuscular abscess formation as infectious focus which remained occult after standard clinical work-up. Conventional chest radiography c, coronal T2-STIR sequence d and axial contrast enhanced T1-VIBE e of a 67-year-old patient with right upper-lobe pneumonia. The radiography shows discrete reticular opacities in the right upper zone suggesting pulmonary infiltration while T2-STIR and contrast enhanced T1-VIBE prove right upper lobe pneumonia as infectious focus. The radiography was taken 1 day prior to the wb-MRI
