Thrombectomy use increasing to treat VTE
The use of arterial and venous thrombectomy to treat blood clots has increased significantly over the past five years, according to research presented November 30 at the RSNA meeting.
Stephanie McNamara, PhD, of Harvard University in Cambridge, MA, presented a study that found procedure rates for venous thromboembolism (VTE) increased by 75% between 2017 and 2022. However, these rates remain low considering the total number of cases per year, McNamara said.
“The incidence of [venous thromboembolism] is expected to grow, creating opportunities to expand the use of these noninvasive procedures,” she noted in a poster p...

PCCT visualizes pulmonary embolism at reduced radiation dose
Photon-counting CT (PCCT) effectively visualizes pulmonary embolism (PE) and reduces radiation dose by 48% compared with traditional CT, according to research presented November 27 at the RSNA meeting.
"[PCCT] ensures confident depiction of acute PE with spectral imaging available at low radiation dose in all patient categories," said presenter Martine Remy-Jardin, MD, PhD, of the University Centre of Lille in France.
Remy-Jardin and colleagues conducted a study that compared performance of traditional CT to PCCT for diagnosing acute PE. The research included a group of patients referred for suspicion of acute pulmonary ...

PCCT improves CTPA exam image quality at lower radiation dose
High-pitch photon-counting CT (PCCT) improves image quality on CT pulmonary angiography (CTPA) for patients with suspected pulmonary embolism (PE) – at lower radiation doses, researchers have found.The results highlight PCCT's potential value for diagnosing suspected PE, according to a team led by Pauline Pannenbecker, MD, of University Hospital Würzburg in Germany."CTPA may benefit from [a PCCT] technique," they noted.Acute PE is a common and often fatal condition, making early detection and treatment crucial, the team noted. CTPA is the go-to test for the diagnostic workup of suspected PE due to benefits such as short...

Road to RSNA 2023: CT
Photon-counting CT (PCCT) has dominated discussion for the last number of RSNA meetings, and this year will be no exception. Expect to hear PCCT research findings about how the technology can increase image quality and lower radiation dose in pulmonary angiography for the diagnosis of pulmonary embolism; how it appears to boost the contrast-to-noise ratio of vascular structures on chest CT; and what it has to offer in the musculoskeletal arena.
Meeting attendees will also get the scoop on the role CT radiomics can play in clinical care, particularly helping clinicians determine the best treatment for patients sufferi...

Pulmonary angiography with PCCT bests conventional CT for PE diagnosis
Wednesday, November 29 | 3:10 p.m.-3:20 p.m. | W7-SSCH08-2 | Room E350
Using photon-counting CT (PCCT) to conduct pulmonary angiography exams is an effective way to diagnose acute pulmonary embolism (PE) at a lower radiation dose than conventional CT, German researchers have reported.
A team led by Pauline Pannenbecker, MD, of University Hospital of Würzburg in Germany conducted a study that included 117 patients who underwent CT pulmonary angiography (CTPA) for suspected PE. Of these, 58 had a PCCT pulmonary angiography exam and 59 had conventional CTPA imaging. The exams were conducted with a 50 ml contrast medium pro...

Road to RSNA 2023: Digital X-Ray
This year’s trip along the Road to RSNA for digital x-ray features mileposts mostly set by AI research. Models will be proposed for applications ranging from predicting bone density on chest x-rays to generating complete reports on anterior cruciate ligament (ACL) tears. Yet several presentations to be given at the meeting reminded us that issues concerning basic elements of x-ray technology remain highly important, as well as whether imaging access is equitable in the "real-world."In one, a group at the University of Washington in St. Louis asked, “How much ionizing radiation are neonatal patients exposed to during ...

Closing the loop on incidental imaging findings
The low completion rate for follow-up recommendations on incidental findings detected on imaging exams has long been a thorny challenge in radiology. In an effort to tackle this problem and increase the percentage of patients who adhere to follow-up imaging recommendations, researchers have identified the factors that influence noncompletion rates and have turned to techniques such as AI and commercial software applications to help close the loop.For example, a group from the University of Rochester in Rochester, NY, recently shared results from using their Backstop recommendation tracking system to directly notify patie...

What Are the Complications of Sickle Cell Trait?
Discussion
Sickle cell disease (SCD) is a group of inherited blood disorders where there are abnormal hemoglobin molecules and the red blood cells take on a characteristic sickled shape instead of a rounded shape. Sickled hemoglobin provides an evolutionary advantage of giving the individual increased protection against severe and cerebral malaria. The sickled shape doesn’t move through the vascular system as well and therefore is more likely to aggregate in small vessels causing an increased risk of vaso-occlusive disease, acute chest syndrome, splenic sequestration, and priapism. There is also an increased risk of ...
