Rayfield Byrd knows when it’s time to wake up every morning. The 68-year-old Oakland, Cal., resident hears a voice from the living room offering a cheery good morning. Except Byrd lives alone. A little after 8 a.m. each day, a small yellow robot named Mabu asks Byrd how he’s doing. Byrd has Type 2 diabetes and congestive heart failure, and about three years ago, he had surgery to implant a microvalve in his heart to keep his blood flowing properly. To stay healthy, he takes four medications a day and needs to exercise regularly. To make sure his heart is still pumping effectively, his doctor needs to stay on to...

ConclusionsMTV and glu-SUVmax measured on pretreatment18F-FDG PET/CT were independent prognostic factors for LD-SCLC patients after chemoradiotherapy with curative intent. These metabolic markers need validation in larger prospective studies but may be useful in the clinical care of LD-SCLC patients.

Abstract PURPOSE: To directly compare the utility for therapeutic outcome prediction of dynamic first-pass contrast-enhanced (CE)-perfusion area-detector computed tomography (ADCT), MR imaging assessed with the same mathematical method and 2-[fluorine-18]-fluoro-2-deoxy-d-glucose-positron emission tomography combined with CT (PET/CT) for non-small cell lung cancer (NSCLC) patients treated with chemoradiotherapy. MATERIALS AND METHODS: Forty-three consecutive stage IIIB NSCLC patients, consisting of 25 males (mean age ± standard deviation: 66.6 ± 8.7 years) and 18 females (66.4 ± 8.2 years...

A 79-year-old woman with a history of anxiety, depression, and chronic obstructive pulmonary disease, as well as a remote history of breast cancer treated with lumpectomy and radiation, presented to her primary care physician with new right upper  quadrant abdominal pain. Abdominal ultrasound identified 3 liver lesions, with MRI confirmation. Computed tomography–guided liver biopsy identified a diagnosis of small cell carcinoma, positive for synaptophysin and chromogranin. Positron emission tomography/computed tomography identified a 3.3- cm left hilar mass with mediastinal lymphadenopathy and concern for lympha...

A low-dose CT scan is the standard diagnostic test for people at high risk of lung cancer. In the United States, about one-quarter of these scans reveal shadows indicating nodules in the lung. Despite that positive result, fewer than 4 percent of those patients actually have cancer.

lah O Abstract A 72-year-old female with no relevant medical history consulted in the emergency room for a two-week history of headache, vomiting and gait disturbance. Head CT scan revealed obstructive hydrocephalus secondary to a pineal mass with compression of the third ventricle. Magnetic Resonance showed another mass located in the right Lushcka foramen. Endoscopic third-ventriculostomy and biopsy of pineal mass were performed. Pathological analysis was consistent with metastasis of carcinoma. Full-body CT scan showed a lung mass related to primary carcinoma. The patient received systemic treatment for metasta...

Abstract Diffusion-weighted magnetic resonance imaging (DWI) has been reported to be useful for the assessment of lung cancer staging. It is uncertain whether DWI is more accurate for the response evaluation of chemotherapy and/or radiotherapy compared to computed tomography (CT). The purpose of this study is to compare the response evaluation of DWI for chemotherapy and/or radiotherapy to recurrent tumors of lung cancer with that of CT which is a standard tool in RECIST (Response Evaluation Criteria in Solid Tumours). Forty-one patients who agreed to this project and had CT scan and DWI examinations within a mont...

ConclusionsSignificant associations emerged between PET features, CT features, and histological type in NSCLC. Texture analysis on PET/CT shows potential to differentiate between histological types in patients with non-small-cell lung cancer.
