Objective:
To assess the ability of a zero-echo time sequence combined with a highly flexible adaptive image receiving coil (AIRTM coil) to visualize pulmonary neoplasms.
Methods:
A total of 42 patients with pulmonary neoplasms were included, all of whom underwent chest CT and MRI examinations. A highly flexible AIRTM coil was used. The MR-ZTE and CT images were compared in terms of subjective and objective image quality.
Results:
Intrapulmonary structures were imaged using MRI-ZTE. Various nodules and masses, including micronodules, subsolid or ground glass opacification nodules, and various masses, were clearly visualized via MRI-ZTE. In terms of subjective image quality, there was no significant difference in lesion detectability between CT and MRI-ZTE (P = 0.8). In terms of objective image quality for MRI-ZTE, the SNRs and CNRs of the lung parenchyma, pulmonary nodules, trachea, peripheral bronchus, and peripheral pulmonary vessels were good.
Conclusions:
MRI-ZTE enabled the detection of intrapulmonary structures and various pulmonary neoplasms with good image quality, including micronodules, subsolid or ground glass opacification nodules, and various masses. Therefore, MRI-ZTE has great potential as a nonradiation alternative to CT for the follow-up of pulmonary neoplasms.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
