The study found that while the CT and HPET images could be co-registered within 2mm in centrally located tumor inserts, tumor inserts on the peripheral were only 8-10mm due to distortion and resolution loss of HPET images. This made it difficult for a therapist to refine treatment volume using the co-registered HPET/CT images.
A study using PET/CT scans found that 58.8% of patients had at least one positive focus of FDG uptake in the thoracic aortic wall, which may indicate 'vulnerable' plaque. This could lead to future cardiovascular events if left untreated.
The study found that higher initial FDG uptake in tumor was associated with poorer prognosis in osteosarcoma patients. Patients identified as having high FDG uptake could be treated more aggressively to improve outcomes.
A study found that nearly 56% of diabetic patients have stress-induced ischemic defects revealed by SPECT myocardial perfusion imaging, regardless of age or sex. These defects were more prevalent in asymptomatic patients than those with a history of chest pain.
Researchers have developed a new radioimmunotherapy cancer treatment that has shown significant promise in treating mantle cell lymphoma. The study found that high-dose therapy resulted in complete remission for seven of eight patients, compared to only one of four with low-dose therapy.
A PET scan study found impaired endothelium-dependent coronary artery vasodilator function in healthy young smokers, indicating increased risk of heart attack and stroke. The study suggests that smoking begins to cause damage much earlier than previously thought, even in those without apparent coronary disease.
A new imaging procedure using a radiotracer has revealed the extent of myocardial tissue injury after a heart attack, even in patients who have been successfully revascularized. The study found that 81% of patients showed persistent cellular damage and 90% had perfusion defects.
H. William Strauss is a pioneer in cardiovascular nuclear medicine and has published extensively on the subject. He recently received the de Hevesy Pioneer Award for his groundbreaking contributions to the field of nuclear medicine.
Dr. Barrio has made significant contributions to Parkinson's and Alzheimer's Disease research, including the first PET study on plaque visualization in living brains. He also supports nuclear medicine research through various committees and publications.
Researchers developed a test to predict which patients with locally advanced breast cancer are likely to respond to chemotherapy, and found it was accurate 100% of the time. The test used radiotracer uptake and washout rates to identify patients who would benefit from specific drugs to boost their response.
Experts will address common misconceptions about radiation and provide guidance on planning and preparation for terrorist acts involving radioactive materials. The seminar aims to educate nuclear medicine professionals and alleviate fears among non-nuclear medical staff.
A new study found that PET scans can reduce unnecessary colorectal surgeries by detecting disease earlier than other imaging modalities. The study analyzed 96 patients and found that PET scans led to active treatment for 12% of them, while conventional imaging indicated rising cancer markers in 10 cases.
A study published in The Journal of Nuclear Medicine found that PET imaging was more accurate than conventional imaging in detecting recurrent breast cancer. PET correctly predicted the outcome in 80% of cases vs. 20% for conventional imaging, with a higher sensitivity and specificity.
A new PET tracer, 11C-acetate, has been found to detect prostate cancer earlier and more accurately than 18F-FDG PET. This breakthrough may enable the detection of cancers that are currently undetectable by conventional methods.
A study found that cardiac stress tests can identify patients at risk of restenosis after stent implantation, with those showing defects experiencing a higher rate of recurrence. The tests also confirmed the efficacy of angioplasty with stent implantation compared to balloon angioplasty.
A new nuclear medicine procedure has received preliminary approval for a clinical trial to diagnose inhalation anthrax in its earliest stages. The technique uses a 99mTc-labeled monoclonal antibody to detect the infection before other diagnostic tests can, enabling early treatment and reducing long-term antibiotic use.
The study found that PET scans changed treatment for 63% of patients with recurrent lung cancer, with a significant impact on patient care and well-being. For newly diagnosed patients, PET results led to changes in staging and treatment planning, impacting 42% of cases.
A study published in The Journal of Nuclear Medicine found that FDG PET detected recurrent thyroid cancer 50% more often than conventional imaging, leading to changes in clinical management for almost 80% of patients. The PET scan identified additional tumor sites and distant metastases, improving patient outcomes.
A new study found that PET scans changed clinical management for 60% of women with recurrent breast cancer, including shifting from surgery to radiation therapy or medical treatment. The scan also significantly impacted disease staging, upstaging 28% and downstaging 8%, leading to more patients being classified as stage IV.
The [18 F]FDDNP PET scan revealed longer retention times of the tracer in areas with high densities of ß-amyloid senile plaques. This finding provides valuable insights into Alzheimer's disease (AD) progression. The image is expected to shed light on disease mechanisms and potential therapeutic targets.
