Significantly lower dose – across clinical areas, patients and operators^a

Making the difference with Live Image Guidance

Every day we see how much of a difference we are making to the quality of people’s lives. And the spontaneous reactions just keep flowing back to us. Today the interventional community is showing us that the AlluraClarity family of X-ray systems with ClarityIQ has fulfilled its ambition and promise.

With 18 peer-reviewed papers and 3840 patients to date, this growing body of evidence reveals one truth: there is significantly lower dose across clinical areas, patients and operators.^a

Interventional neuroradiology

To date, two peer-reviewed comparative studies^1,2 have been performed on a total of 634 patients at the interventional neuroradiology department at Karolinska University Hospital in Stockholm, Sweden. Patients underwent aneurysm repair and arterior-venous malformation treatments, as well as other diagnostic and interventional neuroradiology procedures. These procedures are among the most demanding in the interventional neuroradiology world, requiring images which show very fine anatomical details.

Findings included:

In neuro DSA, ClarityIQ technology reduces patient dose by 75% while maintaining equivalent image quality, compared to an Allura Xper system^1,c,h
In diagnostic and interventional neuro procedures, ClarityIQ technology reduces patient dose by 62% and 65%, respectively, compared to an Allura Xper system^2,c,d

This dose reduction is, at least in my mind a real quantum leap in reducing the dose and improving thereby the procedure both for the patient and for us. I think it's really fantastic."

Interventional cardiology

To date, seven peer-reviewed comparative studies on cardiac interventions have been performed on a total of 2140 patients in various hospitals around the world. The majority were percutaneous coronary interventions. One study each has been performed for pediatric and adult congenital heart disease interventions,⁷ transcatheter aortic valve implantations (TAVIs)⁸ and electrophysiology interventions.¹³

Interventional oncology and vascular

To date, nine peer-reviewed comparative studies have been performed on a total of 966 patients for diverse vascular interventions. These range from adult iliac artery and EVAR procedures to pediatric abdominal procedures. Four peer-reviewed studies have also been conducted for TACE procedures.

Radiation hazards in the interventional suite

Radiation exposure is necessary for life-saving procedures, but with it comes some risk. Patients and physicians are both exposed to high levels of radiation during fluoroscopic procedures. See some best practices for helping manage exposure.

a In 18 individual comparative studies, Philips ClarityIQ was associated with reductions in patient radiation exposure.^1-18

b Relationship between radiation exposure and risk of complications, long-term health risk, procedure time and patient characteristics, procedure complexity, as reported in medical guidelines.¹⁹

c The results of the application of dose reduction techniques will vary depending on the clinical task, patient size, anatomical location and clinical practice. The interventional radiologist assisted by a physicist as necessary has to determine the appropriate settings for each specific clinical task.

d Results based on total dose area product from a single center retrospective, historically controlled cohort study on 614 patients (302 for Allura Xper without ClarityIQ and 312 for Allura Xper with ClarityIQ). Procedural performance (fluoroscopy time and number of DSA images) of the physicians did not significantly differ between the two cohorts.²

e Results based on total dose area product from a single center, prospectively randomized cohort study on 70 consecutive patients (35 for Allura Xper without ClarityIQ and 35 for Allura Xper with ClarityIQ). Number of cine images and contrast medium did not significantly differ between the two cohorts, while fluoroscopy time was significantly higher for the ClarityIQ group. Image quality was based on subjective assessment of two cine runs selected from each patient in two specific projections. Ratings for image contrast, resolution and general appearance were not statistically different. Image noise was more apparent for ClarityIQ images.⁴

f Results based on cine dose area product per frame from a single center prospective study on 39 patients. Cine runs for Allura Xper with ClairtyIQ and Allura Xper without ClarityIQ were acquired on the same patient under same condition of geometry, field of view and injection protocol. Image quality comparison is based on subjective assessment (side-by-side, score: equal or better than the other, blinded review by 6 independent cardiologists).⁵

g Results based on DSA dose area product per frame from a single center prospective randomized study on 48 patients. DSA runs for Allura Xper with ClarityIQ and Allura Xper without ClarityIQ were randomly acquired on the same patient under same condition of geometry, field of view and injection protocol. Image quality was based on subjective assessment (side-by-side, equal or superior than the other, blinded review by 5 independent radiologists).¹⁰

h Results based on DSA dose area product per frame from a single center prospective study on 20 patients. DSA runs for Allura Xper with ClarityIQ and Allura Xper without ClarityIQ were acquired on the frontal and lateral channel on the same patient under same condition of geometry, field of view and injection protocol. Image quality was based on subjective assessment (score 1-5, 1=very poor, 5=excellent, blinded review by 3 radiologists involved in the study).¹

i Results based on total dose area product from a single center prospectively randomized cohort study on 136 patients (68 for Allura Xper without ClarityIQ and 68 for Allura Xper with ClarityIQ). Procedural performances (fluoroscopy time and number of cine images) of the physicians did not significantly differ between the two cohorts.¹³

j Results based on total dose area product from a single center prospective historically controlled cohort study on 101 patients (34 for Allura Xper without ClarityIQ and 67 for Allura Xper with ClarityIQ). Procedural performances (fluoroscopy time and contrast medium) of the physicians did not significantly differ between the two cohorts. ¹¹

k Results based on total dose area product from a single center prospective historically controlled cohort study on 37 patients (18 for Allura Xper without ClarityIQ and 19 for Allura Xper with ClarityIQ). Procedural performances (fluoroscopy time and contrast medium) of the physician did not significantly differ between the two cohorts. ¹¹

l Results based on total dose area product from a single center prospectively randomized cohort study on 50 consecutive patients randomly assigned to the Allura Xper system with ClarityIQ or Allura Xper system without ClarityIQ. Fluoroscopy time and number of DSA images did not significantly differ between the two cohorts. Fluoroscopy and DSA images of each case were subjectively assessed in blinded, offline reading (score 0-5) by three experienced interventional radiologists. DSA image quality was equally rated between cohorts, while fluoroscopy images of Allura Xper with ClarityIQ were slightly (significantly) degraded.¹⁶
