This is a study to determine effectiveness of using catheter directed therapy along with medical directed therapy when treating pulmonary embolism versus using medical directed therapy alone.

The goal of this study is to help compare scans from the new photon counting CT scanner of a solid lung tumor with traditional lab and biopsy results. Subjects enrolled in this study will receive their normal CT scan on the new photon counting CT scanner that has the capacity to provide pictures that are better quality. These images will provide useful information that may lead to future improvements for patients with similar conditions.
