Abnormal imaging findings in TB contacts. a. Participant 2. 61y female, asymptomatic, (i) CXR: normal (ii) PET/MRI: FDG-avid right mediastinal lymph node (SUVmax 3.2); b. Participant 3. 35y female, asymptomatic, (i) CXR: normal (ii) PET/MRI: Spherical FDG-avid lesion in the apex of the right lung (SUVmax 3.9) (iii) Increased signal observed on MRI (HASTE); c. Participant 8. 54y male, asymptomatic, (i) CXR: normal (ii) PET/MRI: FDG-avid right hilar lymph node (SUVmax 2.4) and mediastinal lymph node (SUVmax 2.5); d. Participant 9. [914] 46y male, asymptomatic, (i) CXR: normal (ii) PET/MRI: Diffuse left upper lobe parenchymal uptake (SUVmax 2.2) (iii) No underlying MRI changes; e. Participant 12. 30y male, 1 week of mild non-productive cough, (i) CXR: normal (ii) PET/MRI: Right hilar lymph node (SUVmax 2.6); f. Participant 14. [922] 25y male, asymptomatic, (i) CXR: normal (ii) PET/MRI: RUL parenchymal uptake (1.3) (iii) Small underlying lesion identified on MRI images; g. Participant 16. [924] 22y male, 1 week of mild non-productive cough, (i) CXR: normal (ii) PET/MRI: Patchy right middle lobe parenchymal uptake (2.8), (iii) Bilateral underlying patchy changes identified on MRI. The area of right middle lobe uptake overlies an area of MRI abnormality; h. Participant 18. 46y female, asymptomatic, (i) CXR: normal (ii) PET/MRI: Right hilar lymph node (SUVmax 2.2); i. Participant 30. 66y male, asymptomatic, (i) CXR: normal, (ii) PET/MRI: several FDG-avid hilar lymph nodes (SUVmax = 2.8). (Note that all PET images are SUV images scaled between 0 (white) and 3 (black))
