"Dari pemeriksaan MRI, diperoleh gambar jaringan otak, yang akan digunakan oleh proton MRS untuk menentukan konsentrasi metabolit otak pada jaringan yang didiagnosa astrocytoma, seperti metabolit NAA, choline, creatine, Lipid, Lactate, Myoinositol, dan Glutamine-glutamate. Dari hasil MRS ini, astrocytoma dapat diklasifikasi berdasarkan derajat keganasannya (grade), yaitu high grade dan low grade. Proses klasifikasi astrocytoma, biasa dilakukan secara manual oleh ahli patologi atau secara statistik. Dalam skripsi ini, akan dibahas proses klasifikasi astrocytoma menjadi tiga kelas derajat keganasan dengan menggunakan metode Principal Component Analysis (PCA) dan Spherical K-Means terhadap data MRS. Algoritma Spherical K-Means merupakan algoritma K- Means dengan cosine similarity. Sedangkan PCA merupakan teknik yang digunakan untuk mencari vektor-vektor basis subruang tiap kelas (grade). Vektor-vektor basis ini akan membangun Principal Component yang akan digunakan dalam pengidentifikasian grade suatu data MRS. Data yang digunakan dalam skripsi ini adalah data yang berasal dari laboratorium radiologi Rumah Sakit Cipto Mangunkusumo (RSCM), Jakarta. Hasil penelitian yang dilakukan pada skripsi ini, diketahui bahwa PCA dapat mengklasifikasi astrocytoma dengan akurasi tertinggi, yaitu 85%. Selain itu, dari penelitian ini dihasilkan perangkat lunak yang dapat digunakan untuk membantu pengambilan keputusan yang terkait dengan klasifikasi astrocytoma menjadi high grade, low grade, dan normal.

MRI gives information in form of brain tissue image, which will be used by MRS proton to determine the concentration of brain metabolites on the astrocytoma diagnosed tissue, such as NAA, choline (Cho), creatine (Cr), Lipid (Lip), Lactate (Lac), Myoinositol (MI), and Glutamine-glutamate (Glx). From that result, astrocytoma could be classified to high grade and low grade. This classifying could be processed manually by pathologist, or be processed statistically. On this essay, astrocytoma would be classified into three class of astrocytoma grades with the Principal Component Analysis (PCA) and Spherical K-Means of the MRS data. Spherical K-Means algorithm is a K-Means algorithm with cosine similarity. At the same time, PCA is a technique which used to find the basis vectors of each class (grade) subspace. These basis vectors would build Principal Component which would be used in identifying a grade of a MRS data. The data used in this essay is resourced from radiology laboratory of Rumah Sakit Cipto Mangunkusumo (RSCM), Jakarta. From this research, note that PCA can classify astrocytoma with the highest accuracy, ie 85%. In addition, this research produce software that can be used to assist decision making related to the classification of astrocytoma to high grade, low grade, and normal"

"Latar belakang : CT jantung merupakan modalitas screening pada pasien resiko tinggi penyakit kardiovaskular. Fungsi diastolik ventrikel kiri kurang umum dinilai dibandingkan fungsi kontraksi sistolik ventrikel kiri (ejection fraction, EF). Pasien gagal jantung menunjukkan nilai EF yang baik meskipun pada kondisi stenosis arteri koronaria berat. Mortalitas gagal jantung sama besarnya pada pasien dengan nilai EF normal dan EF menurun, sehingga penilaian dini disfungsi diastolik menjadi hal penting untuk strategi pengobatan yang tepat. Lemak perikardial merupakan faktor prediktor bebas disfungsi diastolik. Penilaian volume lemak perikardial mudah dilakukan, tidak memberikan radiasi dan biaya tambahan, namun tidak rutin dilakukan pada pemeriksaan CT toraks. Penelitian ini melihat hubungan volume lemak perikardial dengan derajat disfungsi diastolik melalui pemeriksaan CT jantung.
Tujuan : Meningkatkan manfaat CT toraks dalam menilai volume lemak perikardial sebagai faktor prediktor disfungsi diastolik.
Metode : Comparative cross-sectional dengan menggunakan data sekunder dari 82 pasien penyakit jantung koroner yang menjalani pemeriksaan DSCT jantung.
Hasil : Terdapat hubungan positif antara volume lemak perikardial dengan disfungsi diastolik derajat sedang pada pasien penyakit jantung koroner yang menjalani DSCT jantung. Titik potong volume lemak perikardial pada disfungsi diastolik derajat berat adalah 220.26cm3, dengan nilai sensitivitas 81.8% dan spesifisitas 74,1%.
Kesimpulan: Volume lemak perikardial dapat digunakan untuk menentukan disfungsi diastolik derajat sedang, dan dapat dipakai sebagai suatu acuan deteksi dini.

Background: Cardiac CT is a modality used for screening patients with high risk of cardiovascular disease by assessing left ventricular systolic contraction function (ejection fraction, EF). It’s still uncommon to assess left ventricular diastolic function. Patients with heart failure showed good EF value despite the severity of coronary artery stenosis. Early assessment of diastolic dysfunction become essential for treatment strategies since there’s equal mortality rate in heart failure patients with normal or decrease EF. Pericardial fat is an independent predictor factor of diastolic dysfunction. Eventhough pericardial fat volume easily assessed and there’s no additional radiation and cost, it still not routinely done in thoracic CT examination. This study looked at the relationship of pericardial fat volume with a degree of diastolic dysfunction through cardiac CT examination.
Purpose: Increase the benefits of thoracic CT to assess pericardial fat volume as a predictor factor of diastolic dysfunction.
Method : Comparativecross-sectional study using secondary data from 82 patients with coronary artery disease who underwent cardiac DSCT.
Result : There is a positive relationship between pericardial fat volume with moderate degree of diastolic dysfunction in patients with coronary artery disease who underwent cardiac DSCT. A cut off value of220.26cm3, determined a sensitivity 81.8% and specivicity 74,1% to detect moderate diastolic dysfunction.
Conclusion: Pericardial fat volume can be used to determine moderate diastolic dysfunction and can be used as a reference for the early detection.

Hubungan asosiasi antara asimetrisitas volume dan asimetrisitas nilai ADC adalah kontralateral dengan hubungan asosiasi cukup kuat (sedang). Penentuan lateralisasi lesi dengan MRI pada masing masing variabel memiliki sensitivitas dan spesifisitas cukup tinggi. Hubungan asosiasi gabungan 2 dan 3 variabel adalah cukup kuat (sedang) dan bersifat ipsilateral, dengan nilai R Kappa, sensitifitas dan spesifisitanya yang lebih tinggi dibandingkan dengan hubungan masing masing variabel.
Kesimpulan: MRI memiliki peranan penting menentukan lateralisasi kejang. Menilai hubungan dari gabungan 2 dan 3 variabel didapatkan secara statistik lebih besar hubungannya dengan lateralisasi kejang dibandingkan dengan menghubungkan masing masing variabel secara terpisah, sehingga penilaian MRI yang dilakukan untuk ke 3 variabel ini akan lebih menguatkan diagnosis sisi hipokampus yang mengalami kelainan.

ABSTRACT
Objective: This study is MRI ( Magnetic Resonance Imaging ) to assess the relationship asymmetry volume, T2WI FLAIR hyperintensity and hippocampal ADC values its relationship with the lateralization of seizures. Routine MRI examination sequences plus a special procedure that hippocampal examination Inversion Recovery sequence T2WI and T2WI Fluid-attenuated inversion recovery ( FLAIR ) can assess hippocampal volume. Sequences DWI ( Diffusion Weighted Image ) and ADC ( Appearent Diffusion Coeffesient ) is a quantitative examination.
Methods: A cross-sectional study using secondary data MRI diagnosis of the patient's head with mesial temporal lobe epilepsy. Volume measurements performed on coronal slice axis parallel to the hippocampus, ranging from the visible head of the hippocampus as much as 5 slices. See picture T2WI FLAIR hyperintensity and measuring the ADC value hippocampus done by placing the ROI on axial cuts at the largest hippocampal ADC map. Data analysis was performed to calculate the value of R Kappa relationship each and combined variable.
Results: There is a fairly strong association relationship (medium) and ipsilateral between T2WI FLAIR hyperintensity volume and asymmetry with lateralization of seizures with R Kappa equal to + 0.52. A weak association relationship and are IPSI lateral with R Kappa + 0.37 between the ADC values with lateralization of seizures. Association relationship between volume and asymmetry value asymmetry ADC is contralateral to the association relationship is strong enough (medium). Determination of lateralization of lesions by MRI in each variable has a fairly high sensitivity and specificity. The combined association relationship 2 and 3 variables are strong enough (medium) and ipsilateral, with a value of R Kappa, sensitivity and spesifisitanya higher than the correlation of each variable.
Conclusion: MRI has an important role determining the lateralization of seizures. Assess the relationship of the combined second and third variables are statistically bigger obtained conjunction with lateralization of seizures compared to connecting each variable separately, so the MRI assessment carried out for 3 to this variable will further strengthen the diagnosis of hippocampal abnormalities., Objective: This study is MRI ( Magnetic Resonance Imaging ) to assess the relationship asymmetry volume, T2WI FLAIR hyperintensity and hippocampal ADC values its relationship with the lateralization of seizures.
