Pulmonary Embolism
|
Which technique is the most effective for diagnosing pulmonary embolism? Research published in the December issue of The Journal of Nuclear Medicine (JNM) suggests single photon emission computed tomography (SPECT), when combined with low-dose CT, may provide an accurate diagnosis-allowing physicians to improve care for patients suffering from this often critical condition by using a diagnostic test that does not expose the patient to a great deal of radiation.

PET on Cocaine
|
When asked to inhibit their response to a "cocaine-cues" video, active cocaine abusers were, on average, able to suppress activity in brain regions linked to drug craving, according to a new study at the U.S. Department of Energy's Brookhaven National Laboratory. The results, to be published in an upcoming issue of NeuroImage, suggest that clinical interventions designed to strengthen these inhibitory responses could help cocaine abusers stop using drugs and avoid relapse.
Above: When active cocaine users watched a video showing people taking cocaine and other cocaine-associated cues, the areas of the brain shown in orange "lit" up, or became more activated an indication that they were craving the drug.

Effect of Proton Pump Inhibitors and H2 Antagonists on the Stomach Wall in 99mTc-Sestamibi Cardiac Imaging
|
The December 2009 issue of the Journal of Nuclear Medicine Technology includes an interesting report of the effect that long-term proton pump inhibitor (ex. Prilosec, Prevacid, etc.) use may have on Tc99m sestamibi biodistribution. Specifically, uptake of radioactivity in the stomach wall that may interfere with myocardial perfusion imaging. The following is the conclusion of the article. Stomach wall activity is completely different from the well-known stomach cavity activity frequently observed secondary to enterogastricreflux of sestamibi. The patients in our study who showed significant stomach wall activity had acid reflux disease of a chronic nature and were taking PPIs. Prolonged PPI therapy, but not H2 antagonist therapy, contributes to a significant increase in stomach wall activity, potentially resulting in Compton scatter or ramp filter artifacts affecting the inferior wall of the left ventricle.Stomach wall activity, unlike the stomach cavity activity, can not be prevented by the ingestion of water before imaging. Other investigators have reported a possible role of a full stomach in diminishing this activity. Therefore, it is important to elicit a history of prolonged PPI use to better anticipate the possibility of increased stomach wall activity, which can confound the image quality and interpretation. The mechanisms explaining this stomach wall activity remain speculative.

Projected Reactor Restart
|
The dormant NRU reactor at Atomic Energy of Canada Limited's Chalk River Laboratories is scheduled for restart and the resumption of medical isotope production by March 2010. The National Research University reactor has been out of service since a small leak of heavy water was detected during routine maintenance last fall.

Peregrine Completes Patient Enrollment in Cotara(R) Dose Confirmation and Dosimetry Brain Cancer Trial |
Peregrine Pharmaceuticals, Inc. (Nasdaq: PPHM) recently reported
completion of patient enrollment in a dose confirmation and dosimetry
trial of Cotara(R) in patients with relapsed glioblastoma multiforme
(GBM), the deadliest form of brain cancer. Cotara is a targeted
monoclonal antibody linked to a radioisotope being developed as a
potential new treatment for GBM. Cotara specifically targets cells at
the center of brain tumors, so its radioactive payload is able to kill
cancer cells while leaving healthy tissue largely unaffected. Cotara is
also being tested in a Phase II clinical trial in patients with
recurrent GBM.

CMS Issues Proposed Decision Memo for PET (NaF-18) to Identify Bone Metastasis of Cancer
|
On November 30, 2009, the Centers for Medicare and Medicaid Services
(CMS) issued a proposed decision memo for PET (NaF-18) to identify bone
metastasis of cancer. In June, CMS opened a reconsideration of Section
220.6 of the National Coverage Determinations Manual to review evidence
on the use of NaF-18 (sodium fluoride-18) imaging (NaF-18 PET) to
identify bone metastasis of cancer. CMS proposes that the evidence is not sufficient to
determine that the results of NaF-18 PET imaging to identify bone
metastases improve health outcomes of beneficiaries with cancer.
Therefore CMS proposes that this use is not reasonable and necessary
under �1862(a)(1)(A) of the Social Security Act (the Act).

Florbetaben Phase III Begins
|
Bayer initiated enrollment for a Phase III trial of PET imaging agent
florbetaben, which zeroes in on beta-amyloid plaques associated with
Alzheimer's disease. The study will have about 400 participants. A
Phase II study showed that the agent can help diagnose the disease in
eight of 10 cases.
