Multidetector computed tomography pulmonary angiography: does arm position affect pulmonary artery enhancement?

Objective: To evaluate whether arm position affects pulmonary artery enhancement in computed tomographic pulmonary angiography (CTPA).

Methods: Study protocol had local ethics committee approval. Eighty-six patients who received 16 detector row CTPA for suspected pulmonary embolism were scanned with their contrast-injected arm resting at their side and compared with 94 patients who were scanned with both arms resting above their head.

Erlotinib and chemoradiation followed by maintenance erlotinib for locally advanced pancreatic cancer: a phase I study.

Objectives: A phase I trial was conducted to determine the maximally tolerated dose of erlotinib with concurrent gemcitabine, paclitaxel, and radiation for patients with locally advanced pancreatic cancer and to gather preliminary data on maintenance erlotinib after chemoradiation.

Methods: Patients received gemcitabine, 75 mg/m2, and paclitaxel, 40 mg/m, weekly for 6 weeks with 50.4 radiation to the primary tumor and draining lymph nodes with a 2- to 3-cm margin.
