Medicare changes, joint meetings spell progress for VC
Virtual colonoscopy is making progress locally in the U.S. as regional Medicare carriers add indications. And a national meeting between the American Cancer Society and colorectal cancer experts promises a new airing of ideas for screening solutions.

Part II: Medical image processing has room to grow
The second installment of our series on 3D and virtual reality, based on talks at the 2006 Computer Assisted Radiology and Surgery (CARS) meeting in Osaka, Japan, discusses fundamental concepts in the development of volume-image modeling.

Echo functionality grows with processing power
Echocardiography, already the most versatile cardiac imaging tool in the box, is poised to get a lot better in the years to come. Many promising applications -- in transducers, miniaturization, and visualization and quantification of cardiac function -- are already developed and operational. More are on the way.

Barriers still hinder lung CAD adoption
A decade into the game, lung CAD appears to work well enough to be considered a serious tool for screening CT lung data. Several studies have shown gains in detecting clinically significant nodules. So why don't more radiologists use CAD in daily practice? There are many reasons, but most revolve around workflow and practice issues rather than the efficacy of CAD itself.

Study pits CT against MRI for virtual colonoscopy
MR colonography offers the promise of radiation-free colorectal exams, excellent soft-tissue contrast, and contrast agents with a better safety profile. But in a polyp-to-polyp face-off in a phantom study, researchers in Germany found that CT colonography (or virtual colonoscopy) still had a sensitivity edge, especially at normal dose levels.

VC visualization tool combines advanced features
Some of the best ideas developed for virtual colonoscopy over the years are being refined and combined to create an advanced exam tool. Researchers from Japan are building Navi-CAD, a comprehensive VC exam system that combines unfolded views of the colonic mucosa, automated polyp detection, and unobserved region detection.

Pulmonary nodule decisions must be individualized
In dealing with the onslaught of pulmonary nodules from multidetector-row CT, radiologists are finding they need to hone their management strategies or risk being inundated. One strategy is based on established size and risk guidelines as well as individual patient factors and nodule morphology. Meanwhile, a new study suggests that gene-expression profiles could potentially improve the management of early-stage lung cancer patients.

New method corrects for hyperattenuation surrounding tagged VC data
Fluid and fecal tagging is a proven method of distinguishing polyps from residual materials in virtual colonoscopy. But tagged, highly attenuated regions tend to "bleed" into adjacent structures on CT images. Researchers from Boston are addressing the problem with a method to electronically subtract the spillover attenuation without otherwise affecting the images.

Health insurance coverage influences breast cancer screening behavior. In one case, a 61-year-old uninsured woman with no known previous screening for breast cancer presented for screening mammography. (A) A craniocaudal two-dimensional synthetic mammogram of the right breast shows an irregular mass in the medial breast with pleomorphic calcifications extending posteriorly. (B) A craniocaudal magnified mammogram more clearly shows the irregular mass and pleomorphic calcifications in the medial breast. (C) An anti-radial ultrasound image of the right breast shows an irregular hypoechoic mass with indistinct margins and posterior acoustic shadowing at the 3 o'clock position, approximately 4 cm from the nipple. (D) An axial postcontrast maximum intensity projection (MIP) subtracted MR image shows a large enhancing mass in the anterior and medial right breast with skin thickening and enhancement and several morphologically abnormal right axillary lymph nodes. (E) An axial postcontrast MIP subtracted MR image with color mapping shows the rapidly enhancing mass with washout kinetic enhancement in the anterior and medial right breast, with skin thickening and enhancement and several morphologically abnormal right axillary lymph nodes. Histopathologic biopsy results demonstrated invasive mammary carcinoma with metastatic disease in a right axillary lymph node. Image courtesy of Peter Abraham, MD, et al.
