ASTRO: Use PET for NSCLC judiciously
By AuntMinnie.com staff writers
PET imaging of non-small cell lung cancer (NSCLC) prior to receiving radiation therapy should not be the basis for determining areas that may benefit from higher doses of radiation, according to research presented today at this week's American Society for Radiation Oncology (ASTRO) conference in Chicago.

Multicenter patient registry shows efficacy of BSGI
By Wayne Forrest
Monday, November 30 | 11:30 a.m.- 11:40 a.m. | VM21-13 | Arie Crown TheaterThis presentation will detail a study at four institutions that found that breast-specific gamma imaging (BSGI) "significantly contributed" to the discovery of malignant or high-risk lesions in patients with negative or indeterminate mammograms.

FDG-PET/CT helps assess pulmonary lymphangitic carcinomatosis
By Wayne Forrest
Friday, December 4 | 11:30 a.m.-11:40 a.m. | SST12-07 | Room S505ABFDG-PET/CT has high specificity for detecting pulmonary lymphangitic carcinomatosis (PLC), while FDG-PET alone can miss focal PLC in close proximity of primary cancer. Those conclusions will be presented by researchers from Massachusetts General Hospital, who observed that FDG-PET showed "significant uptake" in the area of PLC and aided in more accurate diagnoses.

Molecular mammography system could characterize suspicious tissue
By Wayne Forrest
Friday, December 4 | 11:20 a.m.-11:30 a.m. | SST14-06 | Room S403BIn this Friday scientific session presentation, researchers at the University of California, San Francisco will discuss their work on what they call full-field digital molecular mammography (FFDMM), which they hope could be used in conjunction with conventional mammography to characterize malignant from benign tissue.

FDG-PET helps guide treatment of non-small cell lung cancer
By Wayne Forrest
Friday, December 4 | 10:50 a.m.-11:00 a.m. | SST12-03 | Room S505ABResearchers from the University of California, San Diego have conducted a study demonstrating the efficacy of FDG-PET in identifying new lesions and recommend that the modality be used to complement Response Evaluation Criteria in Solid Tumors (RECIST).

PET/CT provides roadmap for software-based registration of MR images
By Wayne Forrest
Friday, December 4 | 10:50 a.m.-11:00 a.m. | SST14-03 | Room S403BRSNA attendees who stay through Friday will be able to attend this scientific session presentation by German researchers who are developing a method of software-based registration of PET and MR images. They hope the technique will allow for reliable identification of the underlying anatomical structure through tracer accumulation.

PET/CT beats 3-tesla MRI for staging colon cancer patients
By Wayne Forrest
Friday, December 4 | 10:40 a.m.-10:50 a.m. | SST05-02 | Room E353CCall it a clash of imaging titans: 3-tesla MRI and PET/CT face off over the staging of colon cancer patients in this study to be presented in the scientific sessions by Italian researchers, who found that PET/CT is more accurate than whole-body MRI.

Sodium fluoride PET/CT changes management of foot pain patients
By Wayne Forrest
Tuesday, December 1 | 3:20 p.m.-3:30 p.m. | SSJ19-03 | Room S505ABIn this scientific session presentation, researchers from Switzerland will discuss how F-18 sodium fluoride PET/CT has the potential to help manage patients with persistent foot pain due to detection of unsuspected active osseous changes.

FDG-PET faces off against MDCT for gallbladder carcinoma
By Wayne Forrest
Tuesday, December 1 | 11:20 a.m.-11:30 a.m. | SSG16-06 | Room S505ABFDG-PET again shows its prowess for cancer diagnosis in this Tuesday scientific session presentation. A Korean research team will discuss its findings, which indicate that the modality is useful to establish the diagnosis of gallbladder cancer and for differentiating inflammatory or benign lesions from malignancy.

PET/CT with C-11 acetate beats FDG for prostate cancer
By Wayne Forrest
Monday, November 30 | 11:20 a.m.-11:30 a.m. | SSC09-06 | Room S504CDIn this scientific session presentation, researchers from Johns Hopkins University in Baltimore will present preliminary data indicating that C-11 acetate PET/CT imaging has higher sensitivity than FDG imaging for detecting primary prostate cancer, local recurrence, and apparent nodal spread in both staging and restaging.

F-18 fluoride PET/CT may offer one-stop shop for bone metastases
By Wayne Forrest
Monday, November 30 | 11:10 a.m.-11:20 a.m. | SSC09-05 | Room S504CDResearchers from India will discuss a study that showed that PET/CT with F-18 fluoride beat other nuclear medicine techniques for detecting skeletal lesions, as well as for distinguishing between benign and malignant tumors, in patients at high risk for skeletal metastases.

Fluoride ion PET/CT beats FDG for metastatic spinal bone lesions
By Wayne Forrest
Sunday, November 29 | 11:45 a.m.-11:55 a.m. | SSA18-07 | Room S505ABResearchers from Stanford University will present a study that concludes that F-18 fluoride ion PET/CT may be helpful in predicting which metastatic lesions will be painful in the thoracolumbar spine. By doing so, the authors say it will allow for more effective treatment planning and could become an alternative to bone scanning with radiopharmaceuticals based on technetium-99m, which is in short supply.
