Comparison of adrenal-to-spleen signal intensity ratios at chemical shift magnetic resonance imaging for benign adrenal lesions (adrenocortical adenomas) versus malignant adrenal lesions (metastases) from lung cancer.

3. Fig. 2
Expected distribution of 100 patients presenting with lung cancer and an adrenal mass, based on 55% prevalence of adrenocortical adenoma in this population, and sensitivity of 96% and specificity of 100% for diagnosing adrenocortical adenoma with chemical shift magnetic resonance imaging (CSMRI). (CT = computed tomography.)

4. Fig. 3
Chemical shift magnetic resonance imaging scan of typical adrenal adenoma. The patient is a 54-year-old woman with poorly-differentiated non–small cell carcinoma. The 1.8-cm left adrenal adenoma (arrow) has a very dark signal because the adenoma contains both water and lipid.

Chemical composition and chemical shift (fast) magnetic resonance imaging (MRI) findings in adrenal adenomas, metastases, and lipomas.

6. Fig. 5
Chemical shift magnetic resonance imaging scan of typical adrenal metastasis from non–small cell lung cancer. The patient is a 70-year-old woman with adenocarcinoma. The 4-cm left adrenal metastasis (arrow) has intermediate signal (similar to that of spleen) because no appreciable amount of lipid is present to cancel the signal from water within the metastasis.
