Telehealth establishes value of connectivity in combat

Telehealth, specifically teleradiology, is becoming more commonplace across the globe, and forward-deployed medical care in wartime is no exception. Theater healthcare may in fact help set an example for austere environments elsewhere, including rural U.S. regions.

Congenital Syphilis

Clinical History: A 29-year-old G1P0 female with poor prenatal care who birthed a 29-week infant via vaginal delivery. The infant had a weak cry, minimal respiratory effort, and an Apgar of 6 at one minute and 8 at five minutes. The baby was intubated and sent to the NICU.

CTA revolutionizes treatment of peripheral vascular disease

We continue to be both amazed and intrigued by the hype showered on cardiac CT angiography and the corresponding lack of hype given to peripheral vascular CTA. No doubt, 64-slice cardiac or coronary CTA is potentially a revolutionizing technology, but PV-CTA has already revolutionized the comprehensive diagnosis and treatment of peripheral vascular disease.

Will patient pics improve or harm interpretation quality?

Radiologists may discover more on CT scans, and feel more connected to patients, when patients' photographs are included with the CT images, according to a study presented at the last RSNA meeting by Israeli researcher Dr. Yehonatan Turner.

Canada develops ambitious electronic health network

Canadian officials estimate that by 2010, at least half of all residents will have their own electronic health record. The EHR is intended to include a cradle-to-grave clinical history, using a single patient identification number. It will eventually be interoperable across the country and its multitiered healthcare delivery organizations. This prediction is not just a political pipedream, as implementation is already well under way.

IHE portable data profile fixes interoperability snags

The shift from film-based images and hard-copy reports to soft-copy reading and digital archiving has sparked challenges when it comes to sharing and distributing data. Referring physicians and patients now typically expect to receive medical data and images on portable media such as compact discs and DVDs. But not all of these portable devices are reliably interoperable with PACS and enterprise IT systems.

Kopans offers point by point rebuttal to Caruncho

I very much appreciate Dr. Caruncho’s thoughtful and detailed response to my article in Diagnostic Imaging. It is ironic I wrote the article before the U.S. Preventive Services Task Force published its new guidelines. Their scientifically unsupportable analysis merely reinforced the concerns I expressed in Diagnostic Imaging.

ER-dedicated practitioners may address workload challenges

We face a defining challenge with regard to the provision of emergency radiology services. Exploding demand for these services comes at a time of relative staffing shortages, declining reimbursements, and rapid technological advancement, and this demand threatens to overwhelm our practices.

MR breast imaging guides interventional procedures

Contrast-enhanced MR imaging has gained recognition in the last decade as a valuable adjunct to both mammography and ultrasound for detection of breast carcinomas. Most authors agree that the sensitivity of breast MRI is excellent, ranging between 88% and 100%, although specificity is only moderate, at 37% to 95%.

Neuroimaging sharpens focus on mild cognitive impairment

Brain imaging markers have emerged as important tools in the differential diagnosis of dementia. Parameters derived from brain imaging are being intensively examined as potential predictors to identify persons with only mild cognitive losses who face imminent decline and the full dementia syndrome of Alzheimer's disease. As novel disease modifying agents emerge, brain imaging markers also may facilitate drug development and help monitor drug efficacy in clinical settings.

Indications expand for fetal MR imaging

Fetal MRI has become established in clinical practice over the past decade. MRI is indicated when conditions do not favor fetal ultrasound such as cases of maternal obesity or anhydramnios.1 It has also been shown that fetal MRI may discriminate among tissue components that do not display impedance differences on ultrasound; for instance, laminae in the developing brain.2 These advantages, along with MR's ability to delineate small structures, such as cranial nerves, has furthered its use as an adjunct to ultrasound in fetal imaging.1 Applications for fetal MRI are growing. The development of improved methods for fetal imaging, including availability of ultrafast sequences,3 has also furthered adoption.
