Prototype automated expert system aids Alzheimer’s disease diagnosis
July 8th 2005A computer-based expert system can diagnose Alzheimer’s disease with an accuracy comparable to experienced nuclear medicine physicians, according to a study presented at the Society of Nuclear Medicine meeting in June.
Whole-body PET/CT proves superior for staging cancers
July 1st 2005Nuclear medicine physicians have suspected since the advent of PET/CT that the hybrid technology would outperform either PET or CT alone for staging cancer. Those suspicions have been confirmed in a study of 260 patients at the University of Essen, Germany. It found that PET/CT is substantially more accurate for staging carcinoma than PET or CT alone and even PET and CT viewed side by side (PET+CT).
Radiologists treating nuclear medicine like a poor stepchild is nothing new
July 1st 2005I read with interest your editorial in the May Diagnostic Imaging ("Funding cuts imperil nuclear medicine's innovative tradition," page 7). I cannot agree more. What we are seeing is not the death knell of nuclear medicine but the consequence of what has been done by physicians themselves. Forever, nuclear medicine has been treated as the poor stepchild of radiology. Until recently, about 80% of nuclear medicine was controlled by part-time radiologists who usually assigned a GED tech to do the nuclear medicine. The physician just countersigned whatever the tech diagnosed. This still left 20%, and since neither discipline controlled the patient flow, nuclear medicine doctors were able to fend for themselves.
CT spots cardiac dysfunction in patients with pulmonary embolism
June 30th 2005Radiologists interpreting scans of patients with suspected pulmonary embolism should check for signs of right heart dysfunction. This action could save a patient’s life, according to a study presented at the American Roentgen Ray Society meeting in May.
Siemens reformulates nuclear medicine into division focused on molecular imaging
June 27th 2005Molecular imaging has been wending its way slowly into the vernacular of nuclear medicine. Now it appears this term may someday supplant nuclear medicine altogether, at least if the recent action by Siemens Medical Solutions is any guide.
CAD holds key to future of CT colonography
June 24th 2005Few radiologists would disagree that computer-assisted detection in the colon has a long way to go before it is ready for routine clinical implementation. But once the remaining technical challenges have been overcome, advocates for CT colonography screening will have a far stronger case, speakers said Friday.
Report from SNM: PET measures brain chemistry associated with bulimia
June 20th 2005PET has linked the behavioral treatment of bulimia nervosa with biochemical activity in areas of the brain associated with addiction and substance abuse, according to a study presented Sunday at the 2005 Society of Nuclear Medicine meeting in Toronto.
Report from MDCT Symposium: Top five features for future CT target clinical developments
June 17th 2005Despite impressive strides, multidetector CT scanner technology could still use some tweaking to maximize its utility, according to a speaker at the seventh annual Symposium on Multidetector-Row CT in San Francisco.
PET/CT proves superior for staging cancers
June 16th 2005Nuclear medicine physicians have suspected since the advent of PET/CT that the hybrid technology would outperform either PET or CT alone for staging cancer. Those suspicions have been confirmed in a study of 260 patients at the University of Essen, Germany. It found that PET/CT is substantially more accurate for staging carcinoma than PET or CT alone and even PET and CT viewed side by side (PET+CT).
IHE committee takes its message around the globe
June 16th 2005Integrating a profusion of digital healthcare information systems is central to providing efficient, high-quality healthcare, and this need spans national boundaries. To address the increasingly global task, the Integrating the Healthcare Enterprise initiative expanded to six new countries last year.
PET will make SPECT irrelevant in 10 years
June 1st 2005When Sir Godfrey Hounsfield introduced CT for brain imaging in 1973, my colleagues and I at the University of Pennsylvania were using a dedicated SPECT instrument, designed and assembled at our institution, to examine blood-brain barrier abnormalities in a variety of neurological disorders.
SPECT/CT imaging raises workflow issues
June 1st 2005The ability to acquire functional and anatomic information in a single scheduled exam offers many clinical and workflow benefits. But making the most of a hybrid imaging system involves far more than simply pressing the "on" switch. With the advent of multislice SPECT/CT, radiologists and nuclear medicine physicians are taking a long, hard look at how these systems will fit into clinical practice.
Next-generation advances push PET/CT into new clinical ground
June 1st 2005A new generation of hybrid scanners has entered the clinical mainstream. Featuring high-performance PET detectors and 16-slice CTs, these systems have followed their predecessors' path into oncology, but they have also veered into new realms.
Oncology benefits from specificity of SPECT/CT
June 1st 2005Nuclear medicine physicians would be the first to admit that the resolution of their color maps could be better. Despite the ability of radioisotope tracers to home in on likely areas of malignancy, poor spatial resolution can hinder precise localization of pathology.
High-resolution CT images sharpen cardiac SPECT
June 1st 2005Combined SPECT/CT scanners are receiving a warm welcome in the nuclear cardiology community. Acquisition of CT data immediately before or after a myocardial perfusion SPECT exam is proving to be an effective means of minimizing attenuation artifacts. Multislice SPECT/CT units could also pave the way to comprehensive assessments of cardiac function.
Anatomic road mapping pinpoints infection sites
June 1st 2005Imaging of infection provides a classic example of nuclear medicine's strengths and weaknesses. Radiopharmaceutical tracers can locate infection sites with great accuracy. As with oncology imaging, however, the absence of anatomic landmarks makes it difficult to determine the location to which the hot spot on a color map corresponds. A better road map, capable of locating the position of signal more precisely, would make it easier to diagnose the cause of infection and plan the most appropriate treatment.
Hybrids generate excitement and sales in evolving nuclear medicine marketscape
May 31st 2005The nuclear medicine market is in a state of flux. Sales were unremarkable last year -- flat for gamma cameras, slightly up for PET/CT scanners -- but new technological advances and product introductions are generating interest as well as new users.
