"This book presents some of the recent advances in Ultrasound imaging technology covering several organs and techniques in a Biomedical Engineering (BME) perspective. The focus of the book is in the algorithms, methodologies and systems developed by multidisciplinary research teams of engineers and physicians for Computer-Aided Diagnosis (CAD) purposes.Cardiovascular and Cancer, the most common life-threatening diseases in western countries, are two of the most important topics focused in the book. However, other advanced issues are also presented such as Intravascular Ultrasound, 3D US and Ultrasound in Computer-Aided Surgery (CAS). Some chapters are direct contributions from medical research groups where Ultrasound has also received great attention in the last decade. By this, new techniques based on Ultrasound were introduced in the clinical practice for diagnosis and therapeutics, mainly in hospital facilities."

"[Penyakit Arteri Perifer (PAP) merupakan sumbatan aliran darah arteri selain koroner dan intrakranial. PAP dihasilkan dari proses atherosklerosis, emboli, trombus, dan inflamasi yang mengarah ke stenosis arteri. PAP asimptomatik menempati 3-10% populasi dunia, dan meningkat hingga 15-20% pada 70 tahun ke atas. Divisi kami mencatat 18,1-24,7% pasien kaki diabetik dengan PAP mengalami amputasi pada kurun waktu 3 tahun terakhir. Evaluasi ultrasonografi Doppler pada arteri utama ekstremitas bawah diharapkan mampu mendeteksi secara dini apakah pasien akan diamputasi atau tidak baik mayor maupun minor. Metode yang diambil adalah analitik komparatif kategorik independen dengan disain penelitian kohort retrospektif. Selama Januari 2010 hingga Desember 2011 didapatkan 24 pasien yang masuk kriteria inklusi. Arteri yang diperiksa a.femoralis, a.poplitea, a.tibialis posterior, dan a.dorsalis pedis dengan tampilan spektral mulai dari monofasik, bifasik, atau trifasik terutama dengan pelebaran spektral. Ultrasonografi salah satu modalitas ?operator dependent?, untuk mengurangi bias, peneliti menggunakan operator ultrasonografi adalah peneliti sendiri, trainee atau konsultan divisi kami. Hasil didapatkan spektral bifasik hingga monofasik pada a.femoralis 25,0%, a.poplitea 58,3%, a.tibialis posterior 41,6%, a.dorsalis pedis 45,8%, angka amputasi mayor dan minor masing-masing 4%. Perhitungan statistik didapatkan untuk a.femoralis p=0,054 (95% CI), a.poplitea p=0,006 (95% CI), a.tibialis posterior p=0,010 (95% CI), dan a.dorsalis pedis p=0,021 (95% CI). Secara statistik, prediksi amputasi dapat bermakna pada ultrasonografi Doppler pada a.poplitea, a.tibialis posterior, dan a.dorsalis pedis. Dapat ditarik kesimpulan pemeriksaan ultrasonografi Doppler penting dilakukan pada setiap pasien PAP untuk mengevaluasi secara khusus keadaan empat arteri utama ekstremitas bawah pasien dan untuk prediktor amputasi

Background: Hepatic vein complication is an important postoperative complication in pediatric liver transplantation in which liver congestion may progress to cirrhosis and graft failure, with higher incidence in living donor liver transplantation (LDLT) compared to other liver transplantation technique.

Objective: This study aims to identify the role of Doppler ultrasound parameters of hepatic vein in early postoperative period of pediatric LDLT as predictors of hepatic vein complications.

Methods: From 2010 to July 2022, there were 44 pediatric LDLT patients in RSUPN Dr. Ciptomangunkusumo who had Doppler ultrasound imaging from first until third postoperative day. Hepatic vein velocity and waveform were compared in patients with and without hepatic vein complications in one year follow up. Cut off point of hepatic vein velocity is determined using receiver operating curve.

Results: Hepatic vein velocity in second postoperative day is significantly lower in patients with hepatic vein complication, with median of 21,3 (16,6-23,3) cm/s compared to 28,9 (10,7-75,0) cm/s in patients without hepatic vein complication (p value = 0,018), with cut off value to differentiate both group is 23,65 cm/s, sensitivity 100%, specificity 76,3%, AUC 0,803 (CI95% 0,679-0,927), and p value = 0,018. There is no difference in monophasic waveform proportion between patients with and without hepatic vein complication.

Conclusion: Lower hepatic vein velocity in early postoperative Doppler ultrasound of pediatric LDLT, especially in second postoperative day, may aid to predict hepatic vein complication in first year follow up. Such finding may increase awareness of hepatic vein complication in the first year after transplantation."

"Latar belakang: Pasien dengan tumor muskuloskeletal (MSK) ganas menunjukkan insidens deep vein thrombosis (DVT) bervariasi. USG Doppler berwarna merupakan modalitas terpilih untuk evaluasi DVT. Tujuan: Menilai hubungan trombus, kecepatan aliran, dan ketebalan dinding vena pada USG Doppler berwarna vena profunda ekstremitas bawah pada pasien dengan tumor primer MSK ganas. Metode: Penelitian ini menggunakan data primer dari pemeriksaan USG Doppler berwarna vena profunda ekstremitas bawah, yaitu trombus, ketebalan dinding vena, dan kecepatan aliran vena, serta data sekunder, yaitu ukuran tumor dari magnetic resonance imaging (MRI) atau computed tomography >(CT) scan dan durasi gejala tumor dari rekam medis. Penelitian dilakukan di Departemen Radiologi dan Poliklinik Orthopaedi dan Traumatologi Rumah Sakit Umum Pusat Nasional Cipto Mangunkusumo (RSUPNCM) bulan Agustus 2020 hingga Maret 2022. Hasil: Terdapat 10% insidens trombus pada sistem vena profunda ekstremitas bawah pada 30 subyek dengan tumor primer MSK ganas. Subyek dengan trombus cenderung memiliki volume tumor lebih besar dibandingkan tanpa trombus, namun secara statistik tidak bermakna. Kesimpulan: Dimensi dan volume tumor pada subyek dengan trombus cenderung lebih besar dibandingkan tanpa trombus. Pada penderita tumor MSK ganas, dapat ditemukan gambaran klinis dan laboratoris yang menyerupai DVT namun belum tentu didapatkan trombus, sehingga USG Doppler berwarna penting untuk membedakan ada tidaknya DVT.

Background: Patients with malignant musculoskeletal (MSK) tumors show variable incidence of deep vein thrombosis (DVT). Color Doppler ultrasound (CDUS) is the modality of choice for DVT evaluation.

Objective: To assess the relationship of thrombus, flow velocity, and venous wall thickness on CDUS of lower extremities deep veins in patients with primary malignant MSK tumors.

Methods: Primary data from CDUS of lower extremities deep vein, including thrombus, venous wall thickness, and venous flow velocity. Tumor size was taken from magnetic resonance imaging (MRI) or computed tomography (CT) scans. Duration of tumor symptoms was taken from medical records. The study was conducted at the Department of Radiology and the Orthopaedi and Traumatology Polyclinic of the Cipto Mangunkusumo National General Hospital (RSUPNCM) from August 2020 to March 2022.

Results: There was 10% incidence of thrombus in 30 subjects. Subjects with thrombus tended to have larger tumor volume but it was not statistically significant.

Conclusion: Tumor dimensions and volume in subjects with thrombus tend to be larger than those without thrombus. In patients with malignant MSK tumors, clinical and laboratory features that resemble DVT can be found, but not necessarily a thrombus, therefore CDUS is important for distinguishing the presence or absence of DVT."
