¹ All authors: Department of Diagnostic and Interventional Radiology, University Hospital Essen, Hufelandstrasse 55, Essen 45122, Germany.

View larger version (136K): [in a new window]   Fig. 1A. —39-year-old man with melanoma. Posteroanterior chest radiograph depicts both lungs as free of disease.

View larger version (124K): [in a new window]   Fig. 1B. —39-year-old man with melanoma. Lateral chest radiograph shows no lung nodules.

View larger version (96K): [in a new window]   Fig. 1C. —39-year-old man with melanoma. HASTE MR image shows pulmonary metastasis (diameter, 6 mm) (arrow) in left lower lung lobe behind heart.

View larger version (102K): [in a new window]   Fig. 1D. —39-year-old man with melanoma. MDCT scan obtained at same level as C shows same lesion (arrow). Metastasis was confirmed on follow-up MDCT scan obtained 3 months later that revealed increase in size.

View larger version (119K): [in a new window]   Fig. 2A. —62-year-old man with renal adenocarcinoma. Posteroanterior chest radiograph shows no lesion in either lung.

View larger version (106K): [in a new window]   Fig. 2B. —62-year-old man with renal adenocarcinoma. Lateral chest radiograph reveals no lesion.

View larger version (155K): [in a new window]   Fig. 2C. —62-year-old man with renal adenocarcinoma. Solitary metastasis with a maximum diameter of 1.9 cm (small arrow) is seen close to pericardium on both MDCT scan (C) and HASTE MR image (D). Note residual pneumonia in right lower lobe (large arrow) which is visible on both images. Third density (arrowhead) with diameter smaller than 5 mm can be seen in lingula on MDCT scan and MR image.

Solitary metastasis with a maximum diameter of 1.9 cm (small arrow) is seen close to pericardium on both MDCT scan (C) and HASTE MR image (D). Note residual pneumonia in right lower lobe (large arrow) which is visible on both images. Third density (arrowhead) with diameter smaller than 5 mm can be seen in lingula on MDCT scan and MR image.

View larger version (143K): [in a new window]   Fig. 4A. —63-year-old woman with renal adenocarcinoma. Posteroanterior chest radiograph presents disseminated pulmonary metastases.

View larger version (103K): [in a new window]   Fig. 4B. —63-year-old woman with renal adenocarcinoma. Lateral chest radiograph also illustrates disseminated pulmonary metastases.

View larger version (116K): [in a new window]   Fig. 4C. —63-year-old woman with renal adenocarcinoma. MDCT scan obtained at level of left atrium shows multiple scattered lung nodules.

View larger version (114K): [in a new window]   Fig. 4D. —63-year-old woman with renal adenocarcinoma. HASTE MR image shows good correlation with MDCT scan (C), even in visualization of small pulmonary nodules.

View larger version (133K): [in a new window]   Fig. 5A. —57-year-old man with testicular carcinoma. Posteroanterior chest radiograph was interpreted as showing bilateral pulmonary nodules.

View larger version (122K): [in a new window]   Fig. 5B. —57-year-old man with testicular carcinoma. Lateral chest radiograph also shows disseminated nodules in lungs.

View larger version (146K): [in a new window]   Fig. 5C. —57-year-old man with testicular carcinoma. Lesion-to-lesion comparison with MDCT scan reveals metastasis (diameter, 5 mm) (arrow) in anterior segment of upper lobe of right lung close to subsegmental vessel.

View larger version (116K): [in a new window]   Fig. 5D. —57-year-old man with testicular carcinoma. On HASTE MR image obtained at same level as C, lesion is not visible.

View larger version (84K): [in a new window]   Fig. 5E. —57-year-old man with testicular carcinoma. Haste MR image shows second MDCT-detected lesion (arrow) near left major fissure.
