Leading German Clinic Praises Photon Counting AB-CT nu:view System

- By Jacqueline Wheeler

Dr Karsten Ridder, Breast Radiologist at MVZ Professor Dr Uhlenbrock and Partner, has described how he and his colleagues were “astonished at the quality of even the very first images” acquired using the AB-CT nu:view Mamma CT System in an interview about the technology in Diagnostic Imaging Europe (DIE). The system uses Direct Conversion photon counting detectors to deliver the outstanding results praised by Dr Ridder in the article,

“Not only does the new system combine a high comfort for the woman being examined with astonishing image quality, but it also does this in a very short examination time. The data speak for themselves: 7000 – 12000 projections per breast in 0.15mm isotropic 3D resolution in a maximum scan-time of 12 seconds. The whole procedure (for both breasts) is carried out in less than five minutes, including contrast media administration. On top of all this, and thanks to the extremely high performance of the photon-counting detector, the average radiation dose is comparable to that of a normal mammogram. It is the only modality which combines 3D visualization of masses, calcifications, architectural distortions and contrast enhancement in one go”.

MVZ Prof Dr Uhlenbrock and Partner has fourteen clinics in, or linked to, hospitals located in the Ruhr area that see around 55,000 women per year. However, Dr Ridder told DIE that “since we have had the Mamma-CT we have noticed that, more and more, patients are being referred to us from all over Europe”.

Dr Ridder and his colleagues were impressed with the system from the start, “The whole set-up process went extremely smoothly, since in principle it is “plug and play” where all primary reconstructions of the 3D-dataset are carried out on the machine’s software and the DICOM headers and images are transferred automatically. We have a high-tech PACS with Syngo-Via, so it is no problem at all to deal with the large amount of data the machine produces (… by the way up to 4 Gigabyte per patient…)”.

However, it was not long before the depth of information that the system was able to reveal began to make an impact, as Dr Ridder explained, “we have come across some cases where the primary diagnosis might have been possible with conventional imaging, but where the real extent of the disease was only detectable with the breast CT. In the first weeks I even had some difficult cases with multifocal carcinomas or complications of implants but which were easily handled by the new system”.

In the opinion of Dr Ridder, patients and radiologists alike at MVZ Professor Dr Uhlenbrock and Partners are clearly benefitting from the installation of the Mamma-CT system with its groundbreaking photon counting technology:

“I am not exaggerating when I say that from my point of view the performance of the Mamma-CT system is simply breath-taking. With every case, the image quality is like something out of science fiction”.
