MRIs in the North American cohort were harmoniously acquired on 3.0-Tesla General Electric Healthcare scanners (Waukesha, Wisconsin). The South Korean cohort underwent MRI within 4 days of stroke onset on a 1.5-Tesla Philips scanner (Philips, Best, the Netherlands). See supplementary Table II for MRI acquisition protocols.
Scanners
Manufactured by GE Healthcare
Scanners are medical imaging devices used to capture detailed images of the body's internal structures. They utilize various technologies, such as X-rays, magnetic resonance, or ultrasound, to generate these images for diagnostic and monitoring purposes.

Patients were selected from the ASPIRE registry, the details of which have been previously reported [10 (link), 11 (link)]. The registry prospectively includes comprehensive clinical and radiological data on patients referred with suspected pulmonary hypertension (PH) to a tertiary referral centre. A total of 225 patients with a heterogeneous mix of normal and abnormal chest CT findings formed the study cohort. All scans were performed on two General Electric (GE) scanners with the patient in a supine position. Scanning parameters included multiple doses and kernels. All patients had thin-slice volumetric scans with contrast in the CTPA protocol. Patients had a diagnosis of either idiopathic pulmonary arterial hypertension (IPAH) or pulmonary hypertension secondary to chronic lung disease (PH-CLD).
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
