Shimadzu Trinias Unity Clinical Use of RSM DSA  

Shimadzu’s Real-Time Smoothed Mask DSA (RSM DSA) is unique Advanced Digital Object Frequency Subtraction for Angiographic Interventional Procedures. RSM DSA provides outstanding vascular visualization with background anatomy information, NO MOTION ARTIFACT even with patient movement or panning the table top. It also automatically suppresses halation of the x-ray radiation during Peripheral Examinations. RSM DSA makes peripheral exams much easier and faster, requiring less radiation dose and contrast.  

Description: SCORETM RSM DSA is Shimadzu’s unique technology developed to overcome motion artifact in DSA imaging. In conventional DSA imaging, a mask image is created before the contrast injection and is subtracted from the LIVE image. Patient movement during conventional DSA acquisition causes misregistration between the two images and creates motion artifact. SCORETM RSM DSA does not require mask image. SCORETM RSM DSA effectively picks up the vessel image by subtracting the background object such as bone which is created by frequency processing the contrast image in real time. The SCORETM RSM DSA image is visualized clearly during patients’ movement and breathing because the core image processing is done during the acquisition of the contrast image. Clinical Usage: SCORETM RSM DSA is most commonly used in visceral, pelvic and peripheral vascular imaging.

Visceral arterial imaging such as imaging of the celiac arteries (including splenic, gastric, and hepatic arteries), superior & inferior mesenteric arteries, and renal arteries sometimes suffer from breathing motion and blurring the details of the vascular subtractions. Similarly, pelvic arterial imaging can suffer from the same effects of motion artifact. Peripheral vascular imaging of the legs often suffers from a different type of patient movement. Injections to visualize the vessels of the legs are frequently done as a bolus injection to fill both legs with contrast. Disease process in the legs frequently causes pain the patient and the result is leg movement and misregistration of the subtracted image. Clinical Benefits: A busy interventional radiology lab like KRMC Interventional Radiology, has a diverse patient population, procedure mix, and imaging needs. KRMC performs a large number of vascular angiography procedures which include liver directed therapies (Yitrium 90, and chemoembolization), peripheral vascular interventions and fistulography. The balance between cutting edge imaging capabilities and radiation dose reduction are crucial, and often are in conflict with each other. The introduction of the Shimadzu SCORETM RSM DSA has changed the fundamental method of acquiring images, while finding ways to save staff and patients from unnecessary radiation exposure. Historically, DSA imaging is used for detailed diagnostic vascular imaging but it requires a very cooperative patient, acquisition of a mask image, and long exposure times. DSA imaging only works properly if the patient can maintain a lengthy breath hold and be motionless through the entire mask/acquisition sequence. Shimadzu’s SCORETM RSM DSA is acquired without subtracting the background with a mask image. Imaging is performed without the need for a mask or with the patient movement restrictions. SCORETM RSM DSA has vastly improved the ability to get high quality diagnostic imaging, especially body imaging where breathing and bowel peristalsis are major contributors to motion artifact. In addition, the operator can pan the table in a manual bolus chase without mis-registering the mask during procedures such as peripheral vascular angiography and fistulography. The result is significantly reduced radiation dose because images can be acquired with one bolus chase acquisition and are not affected by patient motion from pain or involuntary movement that often requires repeat imaging. Routinely, in standard DSA imaging, after obtaining the DSA images, bony landmarks are added back to the image during post processing when reference points are needed. SCORETM RSM DSA does not fully

 Kalispell Regional Medical Center Interventional and Vascular Radiology lab is made up of three interventional fellowship trained radiologists, two radiologist assistants, two angiography suites (one Philips Clarity, and one Shimadzu Trinias), one minor biopsy room, and one GE VCT scanner.

KRMC IR performs roughly 3000-3500 procedures per year. The procedure mix includes vascular and non-vascular imaging with intervention, trauma intervention, drainages, multi organ biopsies, interventional oncologic therapies, thrombectomy including DVT and PE thrombolysis, venous access including dialysis and central venous ports, pain injections, myelography, arthrography, etc.

KRMC is the busiest oncologic center in the state for Liver directed therapies and is major referral center for emergent arterial/venous embolization interventions. Recently, KRMC has developed and built the Montana Children’s hospital which will serve the entire state for emergent, oncologic, and diagnostic pediatric imaging and therapies. KRMC IR will be adding prostate embolization in the near future as well as structuring an embolic stroke therapy program.

subtract bony landmarks and the core image processing is done during the acquisition of the contrast image. SCORETM RSM DSA mixed with the Precession function improves diagnostic ability with reduced radiation exposure. Precession moves the tube in a circular motion around the anatomical iso-center and has been proven to be helpful when performing Uterine Fibroid Embolizations and AV fistulagrams. In AV fistulagrams, the RSM DSA Precession sequence is a great tool to visualize the arterial-venous anastomosis in one acquisition. In a typical DSA acquisition for anastomotic imaging, it may take multiple contrast injections and acquisitions before a proper anatomical profile is achieved. With RSM DSA and Precession together, you can practically fly between all obliquities in one acquisition resulting less ionizing radiation

exposure and contrast dose.

Some types of procedures are more susceptible to movement or need better delineation of the vasculature. Specific examinations that can benefit from using RSM DSA are:

Peripheral vascular angiography/intervention of the abdomen Fistulography/angioplasty Transarterial hepatic chemoembolization

(TACE)/radioembolization Uterine Fibroid Embolization (UFE) Prostate Artery Embolization (PAE) Bronchial Artery Embolization (BAE) Complex Arteriovenous Malformations (AVM) And Complex Arteriovenous Fistula Embolization (AVF)

Case Study #1 Pelvic Angio               

Case Description: 59 y/o male with bilateral iliac artery disease Left iliac stent placed Improved in-flow and distal run-off

       DSA Image with motion                 RSM DSA Image

Procedure Results: On Iliac stenting cases, bowel peristalsis will affect image quality if you are using DSA. With RSM, you are not affected by peristalsis and can more precisely deploy stents. This is especially true in the high common iliac arteries.

Case Study #2 Fistulagrams            

Case Description: 60 y/o Female Fistula stenosis and venous steal embolization. Improved Flow volumes into the 800 ml/min

Procedure Results: The vein is transposed to the artery, so it requires complex angles to see the anastomosis in profile. To clearly visualize the anastomosis without performing multiple different projections, RSM DSA is used in combination with the Shimadzu precession function. The outcome is the patient is delivered less contrast and less ionizing radiation with a higher quality image.

Case Study #3 Cholangiogram  

Case Description: 56 y/o Female with Cholangiocarcinoma needing internalized stent for ductal obstruction. Multiple projections obtained from Precession movement enables us to see stenosis from multiple angles with just one exposure.

Precessional motion series with RSM DSA to visualize ductal obstruction. 

Procedure Results: Cholangiograms are often performed as a dynamic flow diagnosis, that requires visualizing the contrast flow through the biliary ducts while evaluating the speed of the flow. Flow speed provides as much diagnostic value as the static image. The liver is located directly under the diaphragm so breathing motion is always an issue. With RSM DSA, you can obtain a sustained, dynamic image of dynamic contrast flow with no concern about motion artifact.

Case Study #4 Uterine Fibroid Embolization  

Case Description: 43 y/o female with Uterine Fibroids, desire to maintain fertility, symptomatic fibroid. Procedure performed to embolize fibroid to shrink benign fibroid tumor

Procedure Results: Evaluation of the uterine artery is often difficult with conventional DSA due to various branching patterns of its origin, superimposed multiple vessels and motion artifact of the bowel gas. With RSM DSA, uterine artery origins are feasibly identified. It was noted that the patient had variant anatomy. The arterial flow to one of the ovaries was being fed from a 3rd order uterine artery. Placing embo-spheres into the ovary would have resulted in ischemic demise of the ovary. RSM DSA on this case most certainly prevented non-target embolization of the ovary.

Conclusions: SCORE ™ RSM DSA is a unique imaging solution for peripheral vascular, visceral, and pelvic arterial imaging. The partially subtracted image defeats motion artifact by providing detailed

imaging in areas where the patient motion from breathing, peristalsis or body movement interferes with the ability to diagnose the patient. In addition, movement of the imaging system is possible for unique projectional views of the anatomy that are difficult to visualize due to their anatomical position or overlaying vessels.  

The clinical benefits are clear from the case studies presented. In most examinations, a single acquisition with multiple views provides visualization to anatomy that would typically require multiple injections and views to visualize otherwise. Thus, reducing the volume of contrast agent and dose to the patient. Furthermore, time savings in minimally invasive procedures has historically shown to reduce risk and complications to the patient. SCORETM RSM DSA in pace of traditional DSA imaging for multiple exams, helps to solve the everyday imaging problem created by motion. When used in conjunction with specialized c-arm movements, new techniques in imaging are created that were never possible with traditional DSA.
