Frequency and percentage of patients with PMF and lung cancer lesions appearing predominantly as iso- or hypointense on MRI sequences

	PMF, n (%)	Lung cancer, n (%)	p
T1-weighted SE	30 (100%)	2 (6.6%)	< 0.001*
T2-weighted SE	27 (90%)	6 (20%)	< 0.001*
THRIVE	6 (20%)	5 (16.6%)	0.739
BTFE	25 (83.3%)	24 (80%)	1.000
SSH-TSE	21 (70%)	4 (13.3%)	< 0.001*

PMF, progressive massive fibrosis; MRI, magnetic resonance imaging; SE, spin-echo; SSH-TSE, single-shot turbo spin-echo; BTFE, balanced turbo field echo; THRIVE, T1-weighted high-resolution isotropic volume excitation.
