Pulmonary Artery Sarcoma: Diagnosis and Postoperative Follow-Up With Gadolinium- Diethylenetriamine Pentaacetic Acid-Enhanced Magnetic Resonance Imaging Richard B. Rafal, M.D., John N.

Fig. 1 Preoperative axial T1-weighted (repetition time, 750 ms; echo time, 33 ms) magnetic resonance images of 45-year-old woman. A, Mass primarily fills main (short arrow) and proximal right and left pulmonary arteries (long arrows). B, Note enhancement after administration of contrast medium.

Fig. 2 Gadolinium-enhanced magnetic resonance study after initial operation. Coronal (A) and axial (B) views (repetition time, 1,000 ms; echo time, 20 ms) show that intraluminal-enhancing tumor (arrows), although decreased, is still present.

Fig. 3 Magnetic resonance images after second operation. A, Axial T2-weighted (repetition time, 1,714 ms; echo time, 70 ms) image. B, Coronal contrast-enhanced (repetition time, 1,000 ms; echo rime, 20 ms) image. No residual mass or abnormal enhancement is evident in main pulmonary artery (arrows).
