Penelitian ini bertujuan menganalisis prosedur pemeriksaan MRI Brain dengan sekuens Axial 3D T2 SPAIR pada klinis vertigo dan menilai perannya terhadap visualisasi anatomi CPA-IAC. Penelitian menggunakan metode kualitatif dengan pendekatan studi kasus di unit radiologi rumah sakit tempat penelitian. Sampel kasus terdiri atas tiga pemeriksaan MRI Brain klinis vertigo yang telah dianonimkan, sedangkan responden terdiri atas tiga dokter radiologi dan dua radiografer MRI yang dipilih secara purposif. Data diperoleh melalui wawancara terstruktur, telaah SOP, parameter sekuens, citra, dan hasil ekspertise. Prosedur meliputi persiapan dan skrining keselamatan pasien, positioning supine pada head coil, stabilisasi kepala, localizer, sekuens standar MRI Brain, dan penambahan Axial 3D T2 SPAIR. Sekuens ini memiliki irisan 1 mm, akuisisi 3D, kontras T2, penekanan lemak, dan kemampuan rekonstruksi multiplanar untuk membantu menampilkan CPA-IAC, internal auditory canal, kompleks nervus VII-VIII, dan labirin. Tiga sampel menunjukkan variasi temuan sentral dan vaskular, tetapi tidak ditemukan massa CPA-IAC atau kelainan saraf kranialis yang tervisualisasi. Hasil menunjukkan bahwa Axial 3D T2 SPAIR meningkatkan keterbacaan anatomi CPA-IAC secara kualitatif, dengan kendala berupa gerakan pasien, mual, kecemasan, dan tambahan waktu pemeriksaan.
