AI-enabled MRI boosts speed and quality at Kumamoto Chuo Hospital

For Kumamoto Chuo Hospital, Japan, using SmartSpeed technology was their first experience with AI-enabled MRI acquisition. “Before that, we had been using Compressed SENSE, which was a first significant step forward in speed and quality compared to SENSE that we used before,” says Dr. Kazuhiro Katahira, Radiologist at Kumamoto Chuo Hospital. He notes that after the considerable image quality improvement with Compressed SENSE, adopting AI-enabled SmartSpeed has taken fast, high-quality imaging to the next level.

“I like using SmartSpeed because our image quality has considerably improved and the time required for imaging has shortened, making it a very useful technology,” he says. “In my experience, diagnosis has clearly become easier since we started using SmartSpeed. In many instances we have been able to quickly find answers to cases that we had been struggling with in the past.”

Kumamoto Chuo Hospital performs 7000 to 8000 MRI examinations annually. These include a large number of body imaging exams, including approximately 1200 prostate exams, 700 to 800 whole body diffusion exams, as well as liver, bile and fluid exams, and in special cases imaging of the chest area. The hospital uses two Philips MRI machines, a 3.0T Elition and a 1.5T Ingenia.

When SmartSpeed was first employed, it was clear that its AI aspect would be particularly useful. Dr. Katahira explains that it improves the SNR (signal-to-noise ratio) basically by denoising, to create beautiful images. He has identified many advantages. “When higher SNR is not needed, the improved quality can be traded for other benefits, such as shortening the scan time, increasing spatial resolution, sharpening the image quality and many other applications, making it clinically very useful,” he says.

After six months of use, “SmartSpeed is incorporated into all of our examinations. Its clinical advantages are very difficult to sum up in a few words,” according to Dr. Katahira, so he highlights some specific examples: “It helps us in the diagnosis of breast cancer by showing great detail, allowing us to observe development in the breast duct. And in the diagnosis of rectal cancer, it helps us see the invasion of the cancer and the surrounding area in greater detail.”

Many patients who must undergo a lumbar spine examination suffer from back pain.

Speed and high image quality are also important factors determining the diagnostic value of breast MRI. “When the spatial resolution is not high enough for making the diagnosis of breast cancer, a very difficult decision must be made,” says Dr. Katahira. “Since SmartSpeed now allows us to increase the resolution, we can often easily provide a confident answer. In the past with SENSE we used 1.2 mm isotropic voxels in breast imaging after contrast admission. With Compressed SENSE that is 0.8 mm. Now with SmartSpeed we can acquire 0.6 mm isotropic voxels and the images are so clear that even tiny details are clearly visible.”

With SmartSpeed, Kumamoto Chuo Hospital also has the ability to use EPI diffusion-weighted imaging (EPICS-DWI) with Compressed SENSE, which is an important step forward according to Dr. Katahira. “Before, our EPI diffusion was performed using SENSE, but now with Compressed SENSE it is possible to obtain very clear images,” he says.

This is a dramatic improvement for us, because it is now possible to look at slices in various cross section directions. For example, the presence or absence of venous invasion is very important in rectal cancer patients, because venous invasion can cause metastasis in the future. The ability to reconstruct images according to the direction of the blood vessels, allows us to see venous infiltration more realistically, which is a world of difference from what we were used to.”

MotionFree abdominal scansSmartSpeed helps achieve imaging that used to be problematic before. “When patients have difficulty holding their breath, for example in upper abdominal examinations, it is often not possible to perform an MRI examination,” says Dr Katahira. “However, with SmartSpeed we now have various ways to accomplish it. A direct benefit to these patients is the shorter scan time possible. The motion-free techniques allow us to now acquire clean single shot images. We have seen that this helps many such patients complete the examination.”

Performed on Elition X.Images of the upper abdomen can easily get blurred due to the patient’s breathing. Before SmartSpeed a viable alternative method was lacking. “We like to use single shot T2-weighted images but in the past these would look like heavy T2-weighted images, which is why we added halfscan, but this often introduced blurring,” says Dr. Katahira. “So there was a limit to what could be done. Now, with SmartSpeed, the reduction factor can be increased, so halfscan can be turned off, and sharp images can be obtained. A single-shot T2-weighted image can be taken in about 10 seconds. Because of their high resistance to movement, acquiring multiple of these images can be a substitute, even if there is some patient motion. So, thanks to SmartSpeed, we can now obtain sharp single shot images without halfscan, making single shot a good alternative to multishot.”

Also in dynamic MRI of the liver Dr. Katahira sees important improvements.

He indicates this is very useful for the radiologist when diagnosing, especially because it can provide a high temporal resolution.
