Statistics can be remarkable things. They can identify the benefit of current actions or point to new paths for the future. The statistics released last week by researchers at Memorial Sloan-Kettering Cancer Center in New York exemplify the former. Statistics that could be garnered from the use of healthcare IT exemplify the latter.

Stentor merges with PhilipsOne month after Philips Medical Systems announced its intention to buy Stentor, the Dutch company has completed the acquisition. The merger will strengthen Philips’ position as a primary supplier of healthcare IT. Philips previously had depended on Swedish IT specialist Sectra for its PACS and workstation products (DI SCAN 7/18/05). In announcing the acquisition, Philips claimed record quarterly revenue for Stentor over the past three months, highlighting 14 new customer contracts, including a seven-year contract renewal from Henry Ford Health System.

I saw the article that you coauthored on the digital breast imaging forum at SCAR ("Breast imagers come out swinging against digital mammography vendors," diagnosticimaging.com/scar2005/, June 7, 2005. An expanded version appears in the SCAR Conference Reporter, this issue, page 54). I am very happy that you were there and interested in digital mammography. Also, I am pleased that you described the struggles we are having on the clinical side so accurately.

In a delicate dance between open discussion and sheer frustration, all players in the digital mammography arena, from users to vendors, wrangled over evolving technology issues during a marathon forum at the SCAR meeting. Among the points of contention was the speed at which the technology is achieving consistent image quality standards.

One of the pioneers of digital mammography, Fischer Imaging, is exiting the market. The company has signed a definitive agreement to sell Hologic the intellectual property and customer lists of its mammography business and products. The cash purchase price of $32 million includes the rights to Fisher’s SenoScan digital mammography and MammoTest stereotactic breast biopsy systems.

Despite the increasing availability of commercial computer-assisted detection packages for breast screening, the technology remains unproven in the screening setting, according to a leading U.K. breast radiologist. Prof. Fiona Gilbert, a professor of radiology at the University of Aberdeen, is calling for a Europe-wide randomized control trial to prove the case for CAD as a second reader.

A significant number of breast cancers missed by mammography in the last decade may have been misclassified as benign lesions by ultrasound in the first place, according to a study presented at the 2005 American Institute of Ultrasound in Medicine meeting.

Few 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.

The true value of widespread mammography screening is a contentious issue, with claims for its success difficult to disentangle from coexisting factors. Now, research from Denmark has produced the strongest evidence to date that screening produces significant re-ductions in breast cancer mortality.

Full-field digital mammography has turned into a superstar of x-ray, doubling in revenue and units shipped last year over 2003. Growth is expected to continue, although the pace may slow as the backlog of ordered systems shrank by year’s end to just 10% more than the number shipped.

The Institute of Medicine has recommended sweeping changes to quality standards now being applied to breast imaging facilities. If Congress, which requested the study, enacts these changes, facilities will face a substantially greater burden in collecting patient data, potentially increasing the need for information technology.

Siemens closes in on CTI acquisitionAs of May 4, 94% of the outstanding shares of CTI Molecular Imaging had been acquired by Siemens Medical Solutions as part of that company’s bid to acquire the Knoxville, TN, firm. Siemens expects to complete the acquisition through a merger in which all CTI shares not validly tendered will be converted into the right to receive $20.50 per share. CTI would then become a wholly owned subsidiary of Siemens Medical Solutions. CTI Molecular Imaging is a supplier of PET products and services with annual revenues above $400 million and annual income near $60 million.
