Primary lung cancers <1 cm found with MR screening appeared larger with half-Fourier sequences than with three-dimensional acquisition techniques

“…Therefore, it is better to evaluate both sequences, particularly in patients with known primary malignancy. The T1W 3D-GRE sequence has better spatial resolution and is helpful in evaluating lung parenchyma, particularly for detection of small (< 1 cm) pulmonary nodules [6,7,11,12]. Pulmonary nodules often show progressive retention of contrast, increasing their conspicuity on delayed phase images [11].…”
