Background:Stroke causes mortality and disability. Thrombolytic therapy is standard
for ischemic strokes up to 4.5 h after symptoms. Although artery occlusion can be
diagnosed by DSA, MRA, and CTA, thrombus composition and development
timeframes may not be known. SWI is used to detect thrombus in acute ischemic stroke.
SWI can indicate a thrombus as a hypointense SVS.Wecompared the detection of
hemorrhage by using susceptibility weighted imaging (SWI) with T1, T2 and Fluid
attenuation inversion recovery (FLAIR) sequences in acute stroke.
Materials and Methods: From October 2020 to October 2021, 150 patients with
suspected acute stroke were examined prospectively at Kakatiya Medical College/MGM
Hospital Warangal using the above sequences. Acute infract haemorrhage detection was
evaluated and compared.
Results: In 58 individuals, 48 had arterial infarcts and 10 had venous infarcts.
Hemorrhage affected 38 (25.33%) of 94 male patients and 18 (12%) of 56 female
patients.When compared to T1, T2, and FLAIR, SWI was significantly more sensitive
and specific (p value 0.0031) for detecting haemorrhage in acute infract. There were 26
(17.33%) cases of Susceptibility sign, which indicates an intravascular thrombus.
Conclusion: SWI is the most effective sequence for detecting haemorrhage in acute
infracts. It can also determine the source of an infraction by detecting the susceptibility
sign. The SWI sequence must be included in the protocol for evaluating patients with
acute stroke.
