Response to Granja et al Letter, “Increased Versus Appropriate Neuroimaging Utilization in Stroke: A Complex Matter.”
We thank the authors for their comments [1] and for raising several important issues about our article on the updated trends, sociodemographic disparities, and impact of stroke neuroimaging on mortality across the United States from 2012 to 2019 [2]. Their letter reminds readers about our findings of significantly increased utilization of CT angiography (250%), CT perfusion (428%), and MRI (18%) as well as decreased use of MR angiography ( −33%) in stroke patients. Furthermore, our consistent and extensive data on disparities across specific demographic groups (ie, rural patients, patients ≥80 years, female patients, a...

Upward Utilization Rates of Neuroimaging in Ischemic Stroke in the Last Two Decades: Improving Patients ’ Outcomes or Increasing Health Care Cost?
There has been an increase in imaging utilization rates over the last few decades [1], with Medicare enrollees ’ utilization increasing at a higher rate compared with commercially insured individuals [2]. This increase is likely due to technical improvements, improved availability and access to scanners, physician and patient demand, and at times financial incentives [2]. Although imaging benefits include accurate disease diagnosis, improved treatment decision making, and health outcomes, it can also be associated with increases in costs and other patient harms, including incidental findings, overdiagnosis, anxiety, and ...

Increased Versus Appropriate Neuroimaging Utilization in Stroke: A Complex Matter
We read with great interest the study by Wang et al [1], in which they reported updated trends, sociodemographic disparities, and the impact of stroke neuroimaging on mortality across the United States from 2012 to 2019. They found a significantly increased utilization for CT angiography (250%), CTP (428%), and MRI (18%) as a well as a decreasin g rate for MR angiography use (−33%) in stroke patients. The way that the authors present consistent and extensive data on disparities across specific demographic groups (ie, rural patients, ≥80 years, female and black patients) has a significant value in designing effective ...

Rapid Response to the Acute Iodinated Contrast Shortage During the COVID-19 Pandemic: Single-Institution Experience
Modern health care depends upon the use of radiologic imaging for diagnostic and therapeutic purposes. Iodinated contrast media (ICM) is used in radiology primarily for CT and fluoroscopy-guided procedures. Outside radiology, other services that use ICM include cardiology, vascular surgery, neurology, urology, and gastroenterology. Quaternary care academic medical centers with level I trauma services, comprehensive stroke centers, and ST-segment elevation myocardial infarction services all rely heavily upon a steady supply of ICM to treat patients.

Striving for Socioeconomic Equity in Ischemic Stroke Care: Imaging and Acute Treatment Utilization From a Comprehensive Stroke Center
Prior studies have shown socioeconomic disparities in advanced neuroimaging and acute treatment utilization in patients with ischemic stroke. The authors analyzed whether socioeconomic factors were associated with stroke neuroimaging and acute treatment utilization at a comprehensive stroke center.

Radiology Operations —The Role of Cost-Effectiveness Studies in Decision Making
Radiology leaders are under a lot of pressure when it comes to decision making, continuously trying to meet the needs of radiologists, referring providers, patients, and hospital administrators. For example, when it comes to choosing an imaging algorithm for patients with stroke, stakeholder interests may collide: Patients and treating physicians require a fast workup, radiologists value high accuracy of the imaging modality, and hospital administrators struggle to provide a setting where MRI is accessible 24-7.
