From: Value of ultrasound fusion imaging in detecting vascular cerebral white matter pathology
Fusion procedure of ultrasound (US) and MR images. The ipsilateral middle cerebral artery (MCA) is determined as anatomical landmark. After US visualization of the ipsilateral MCA in color-coded duplex ultrasonography (TCCS), axial scanning approach, US images are fused with the corresponding MR images (TOF-sequence) and corrected, if necessary, to match perfectly (a–c). During UFI investigation MR FLAIR images are used for online examination (d–f). a–c: Left: TCCS MCA ipsilateral. Middle: MR TOF angiography. Right: Fused images. d–f: Left: TCS in B-Mode. Middle: cerebral MR FLAIR image, axial plane. Right: fused images US and MRI. White matter lesions (WMLs) II, Anterior horn contralateral. White arrows indicate the WMLs
