"Recent advances in MR technology permit the application of diffusion MRI outside of the brain. In this book, the authors present cases drawn from daily clinical practice to illustrate the role of diffusion sequences, along with other morphological and functional MRI information, in the work-up of a variety of frequently encountered oncological and non-oncological diseases. Breast, musculoskeletal, whole-body, and other applications are covered in detail, with careful explanation of the pros and cons of diffusion MRI in each circumstance. Quantification and post-processing are discussed, and advice is provided on how to acquire state of the art images, and avoid artifacts, when using 1.5- and 3-T magnets. Applications likely to emerge in the near future, such as for screening, are also reviewed. The practical approach adopted by the authors, combined with the wealth of high-quality illustrations."

Background: Correlation between preoperative left ventricular end diastolic volume index LVEDVi with short term postoperative outcome after surgical secundum atrial septal defect ASD closure has never been explored. Our aim is to determine the correlation between preoperative LVEDVi and short term postoperative outcome after surgical ASD closure.

Objective: To determine the correlation between preoperative LVEDVi and short term postoperative outcome after ASD closure.

Methods: We analyzed all consecutive surgical ASD closure patients who underwent cardiac magnetic resonance imaging MRI previously with 1.5 T Philips Medical System Scanner with 32 elements phase sense torso cardiac coil between January 2013 December 2017.

Results: There were 30 patients who fulfilled inclusion and exclusion criteria who had weak negative correlation but significant r 0,365, p 0,048 between LVEDVi and with postoperative intensive care unit ICU length of stay LOS days , nonsignificant weak or very weak negative correlations with other outcomes.

Conclusion: LVEDVi had a weak negative correlation with ICU LOS post surgical closure of secundum ASD and a very weak negative correlation with other outcomes."

"Latar Belakang: Telah diketahui infeksi COVID-19 dapat menetap menjadi sindroma pasca COVID-19. Magnetic Resonance Imaging (MRI) kardiak memiliki nilai diagnostik tinggi untuk menilai karakteristik jaringan miokard. Belum diketahui secara pasti efek jangka panjang COVID-19 terhadap jaringan miokardium serta faktor-faktor admisi yang memiliki pengaruh terhadap prevalensi sindroma pasca-COVID-19 pada populasi dengan penyakit kardiovaskular. Tujuan: Mengevaluasi prevalensi fibrosis miokardium dengan MRI kardiak pada pasien dengan penyakit kardiovaskular dan riwayat COVID-19 1 tahun pascaperawatan, serta mengidentifikasi faktor admisi yang berpengaruh terhadap fibrosis miokardium. Metode: Kohort prospektif dengan menilai parameter MRI kardiak pada pasien terkonfirmasi COVID-19 dengan penyakit kardiovaskular 1 tahun pascaperawatan. Selanjutnya, dilakukan analisa temuan MRI kardiak terhadap kelompok kontrol tanpa riwayat COVID-19 yang telah di-matching berdasarkan umur, jenis kelamin, dan faktor resiko. Analisa multivariat dilakukan untuk mengetahui faktor admisi yang memiliki hubungan dengan kejadian fibrosis miokardium. Hasil: Total 32 subjek dengan penyakit KV dan riwayat COVID-19 1 tahun pascaperawatan dengan 49 subjek kontrol disertakan dalam studi ini. Terdapat peningkatan yang signifikan pada parameter MRI kardiak yaitu proporsi abnormal T1 relaxation time (65,5% vs 36,7%; p-value=0,011) serta late gadolinum enhancement (LGE) skar noniskemik 62,5% vs 29,8%;p-value=<0,001) pada kelompok dengan riwayat COVID-19 dibanding kontrol. Tidak ditemukan faktor admisi yang berpengaruh terhadap peningkatan LGE noniskemik/T1 abnormal. Kesimpulan: Terdapat peningkatan prevalensi fibrosis miokardium pada pasien dengan penyakit KV dan riwayat COVID-19 1 tahun pascaperawatan dibanding kontrol dinilai melalui MRI kardiak. Tidak terdapat hubungan antara faktor admisi dengan fibrosis miokardium 1 tahun pascaperawatan COVID-19.

Background: Presently, it has been acknowledged that COVID-19 infection may persist longer as Post-acute COVID-19 Syndrome. Cardiac Magnetic Resonance Imaging (cMRI) possesses a high diagnostic value to evaluate myocardial tissue characteristics. Data are still limited regarding longer implications of COVID-19 infection towards myocardial tissues and predictive admission factors in patients with Cardiovascular Diseases (CVD).

Aim(s): To evaluate the prevalences of myocardial fibrosis using cMRI in patients with CVD and one year post-COVID-19 hospitalization and identifying admission factors in correlation with myocardial fibrosis. 

Method(s): Prospective cohort to assess cMRI parameters in patients with CVD and history of COVID-19 one year post-hospitalization. The results were then compared with the age-, sex-, risk factors-matched control group without prior of COVID-19 infection. Lastly, multivariat analysis was done to identify relations between admission factors and myocardial fibrosis. 

Result(s): A total of 32 subjects with CVD one year post-COVID-19 hospitalization and 49 controls were included in this study. Significant increases of cMRI parameters, namely abnormal T1 relaxation time (65.5% vs 36.7%; p-value=0.011) and non-ischemic late gadolinum enhancement (LGE) (62.5% vs 29.8%;p-value=<0.001) were observed in the population with prior COVID-19 infection compared to control. No admission factors were found to be related with the increases in nonischemic LGE/abnormal T1.

Conclusion: There is a significant increase of myocardial fibrosis prevalence in patients with CVD one year post-COVID-19 hospitalization compared to control assessed through cMRI parameters. No relationships were found between admission factors and myocardial fibrosis. "

"Pada kasus lumbal spinal stenosis, penentuan terapi dibedakan menjadi konservatif termasuk medikamentosa dan rehabilitasi medik dan pembedahan. Secara general, pembedahan dilakukan pada pasien yang tidak mengalami perbaikan klinis setelah menjalani terapi konservatif. Tesis ini membahas perbedaan gambarandegenerative lumbar spinal stenosis berupa pengukuran faktor determinan menggunakan MRI lumbosakral pada pasien yang menjalani pembedahan kelompok uji dan konservatif kontrol. Pengamatan perubahan radiologis yang akurat akan membantu klinisi memperkirakan terapi yang sesuai untuk pasien secara lebih dini dan efektif. Sebagai hasil, secara bivariat, faktor determinan yang bermakna adalah stenosis kanalis lumbal L3-4; stenosis recessus lateral L4-5 dan L5-S1; stenosis foraminal L3-4 bilateral dan L5-S1 kiri; hernia nukelus pulposus L3-4 dan L5-S1, hipertrofi ligamentum flavum L3-4 dan degenerasi sendi facet L4- 5 kanan. Dengan analisa multivariat, didapatkan hanya hernia nukelus pulposus L3- 4 dan L5-S1 saja yang menentukan keputusan operasi.

In degenerative lumbal spinal stenosis, choice of treatment divide into conservative with medication and rehabilitation included and surgical. Generally, surgery to patient perform when there is no improvement in clinical examination after adequate conservative treatment. In this thesis, we describe difference in determinant factors seen with MR study to patients with lumbar spinal stenosis who had surgical treatment case group and conservative treatment control group. Carefull observation in radiologic changes will help clinician to predict patient outcome and decide adequate treatment. As results, using bivariate analysis, we conclude that there are significantly differences in lumbal canal stenosis at L3 4 level lateral recessus stenosis at L4 5 and L5 S1 level, foraminal stenosis at L3 4 bilaterally and at left side of L5 S1 level hernia nucleus pulposus at L3 4 and L5 S1 level flavum ligament hypertrophy at L3 4 level and facet joint degeneration at right side of L4 5 level. Meanwhile, using multivariate analysis, only hernia nucleus pulposus of L3 4 and L5 S1 level bring decision to surgery."
