MR evaluation of chest wall involvement in malignant lymphoma.

abstract：PURPOSE:The purpose of this work was to assess whether easily obtained clinical parameters can predict optimal scan delay for contrast-enhanced spiral CT of pulmonary arteries and to compare image quality between individualized contrast timing versus a fixed scan delay. METHOD:We used an individualized delay in 85 pat...
