"The book is divided into three parts: 1. Anatomy, which covers relevant sonographic anatomy in the head and neck (with complementary images from CT, MRI); 2. Diagnoses, the core content of the book with detailed sonographic description of common Head &​ Neck lesions, key clinical information and practical scanning tips towards identifying the wide spectrum of diseases in this region; 3. Differential Diagnoses, which provides differential diagnoses for common sonographic signs/​appearances. Although the book is on ultrasound, readers will find images from other imaging modalities so as to highlight the importance of multimodality imaging in modern clinical practice. This book is a compilation of Head and Neck sections of three previous books published by AMIRSYS, namely Diagnostic Imaging: Ultrasound; Diagnostic and Surgical Imaging Anatomy: Ultrasound and Expertddx: Ultrasound. The text &​ images (over 400) in the Anatomy section of the book remain relatively unchanged from the earlier book. In addition to the twenty diagnoses in the Diagnostic section of the earlier book, twenty one new diagnoses/​chapters have been added. This entire section of the book now contains over a thousand images (almost all of these are new images with comprehensive annotation), in particular, illustrative images of shear wave elastography &​ strain imaging have been included. The key facts box feature of the book remains in this section &​ is ideal for a quick review for readers with short attention spans. The Expertddx section of this book has over two hundred &​ fifty images (half of which are new) &​ includes key references"

"Latar belakang dan tujuan : CT scan merupakan modalitas pencitraan utama pada berbagai tumor primer kepala dan leher serta ketersedian modalitas CT yang lebih luas di Indonesia. Penelitian ini bertujuan untuk mendiskusikan peranan CT sebagai modalitas yang berpotensi membantu menegakkan diagnosis keterlibatan lokoregional kelenjar getah bening KGB leher sehingga didapatkan perencanaan tatalaksana karsinoma sel skuamosa KSS dengan nilai terapi dan prognosis terbaik. Penelitian ini modifikasi Choi dan meneliti kesesuaian antara kriteria diagnostik KGB metastasis pada CT scan dibandingkan dengan hasil histopatologik pada pasien KSS. Metode : Penelitian ini merupakan studi asosiatif secara potong lintang pada data primer kasus baru KSS-KL. Pengambilan data berlangsung dari bulan Februari 2018 hingga April 2018 di Poli Onkologi Departemen THT, Departemen Radiologi dan Departemen Patologi Anatomi RSUPN Cipto Mangunkusumo. Sebanyak 90 unit sampel dievaluasi lokasi, morfologi dan kemungkinan metastasis pada CT scan preoperatif menggunakan kriteria diagnostik, kemudian tiap unit sampel diberi label untuk menunjang kesesuaian node-per-node yang kemudian disesuaikan dengan KGB temuan intraoperasi. Operasi diseksi leher dilakukan dengan jarak kurang dari 1 minggu pasca CT scan preoperatif. Pasca diseksi, setiap KGB yang telah diberi label dilakukan pemeriksaan histopatologik. Kemudian asumsi kesesuaian temuan pada CT scan preoperatif dan histopatologik diuji hipotesis komparatif menggunakan uji McNemar. Hasil : Penelitian ini menunjukkan nilai p = 0,000 yaitu terdapat perbedaan bermakna antara kriteria diagnostik KGB maligna pada CT scan dengan histopatologik. Penilaian kesesuaian kriteria diagnostik KGB maligna pada CT scan dengan histopatologik menggunakan Kappa didapatkan R = 0,12 p=0,100 . Kriteria diagnostik KGB maligna pada CT scan pada penelitian ini memiliki nilai sensitivitas 33,3 dan nilai spesifisitas 61,7 dengan nilai spesifisitas ukuran aksis pendek, hipodensitas dan penyangatan heterogen masing-masing 100 dan nilai sensitivitas lokasi drainase primer 100 . Kesimpulan : Tidak terdapat kesesuaian antara kriteria diagnostik KGB maligna pada CT scan dengan hasil histopatologik. Adanya komponen kriteria diagnostik yang sangat sensitif tapi tidak spesifik dan yang sangat spesifik tapi tidak sensitif menyebabkan nilai sensitivitas dan spesifisitas kriteria diagnostik ini rendah.

Background and Objective CT scan is the main imaging modality in various head and neck primary tumors and broader availability in Indonesia. This study aims to discuss CT as a modality that helps establish the diagnosis of lymph node metastases so the management of head and neck squamous cell carcinoma HNSCC can be done with the best therapeutic value and prognosis. This study of Choi modification is trying to research about association between diagnostic criteria of metastases lymph node in CT Scan and histopathologic in SCC Patients Methods This research is a cross sectional associative study on the primary data of the new case of HNSCC. Data collection took place from February 2018 to April 2018 at the Polyclinic Oncology Department of ENT, Department of Radiology and Department of Pathology Anatomy Cipto Mangunkusumo Hospital. A total of 90 sample units were evaluated for location, morphology and possible metastasis on preoperative CT scans using diagnostic criteria, then each sample unit was labeled to support node per node association which was then adjusted to intraoperative lymph node findings. Neck dissection surgery is performed less than 1 week after a preoperative CT scan. After the operation, every lymph node that has been labeled is carried out to histopathologic examination. Then the hypothesis of association of the findings on preoperative CT scans and histopathologic is tested using McNemar test. Results This study shows p value 0,000 so that there is a significant difference between the diagnostic criteria on CT scan and histopathologic examination. Assessment of the diagnostic criteria for malignant KGB on CT scans and histopathologic examination using Kappa obtained R 0.12 p 0.100 , which shows no suitability between them. The diagnostic criteria for malignant lymph node on CT scan in this study have a sensitivity value of 33.3 and a specificity value of 61.7 with a specificity value of the size of the short axis, hypodensity and heterogeneous enhancement respectively 100 and the sensitivity value of the primary drainage site 100 . Conclusion There is no agreement between the diagnostic criteria for malignant lymph nodes on CT scan with histopathologic examination. The existence of a highly sensitive but non specific and a highly specific but insensitive component of the diagnostic criteria might causes the sensitivity and specificity of these diagnostic criteria to be low."

"Written by internationally renowned experts, this volume is a collection of chapters dealing with imaging diagnosis and interventional therapies in neuroradiology and diseases of the spine. The different topics are disease-oriented and encompass all the relevant imaging modalities including X-ray technology, nuclear medicine, ultrasound and magnetic resonance, as well as image-guided interventional techniques. It represents a unique experience for residents in radiology as well as for experienced radiologists wishing to be updated on the current state of the art."

"Imaging is crucial in the multidisciplinary approach to head and neck cancer management. The rapid technological development of recent years makes it necessary for all members of the multidisciplinary team to understand the potential applications, limitations, and advantages of existing and evolving imaging technologies. It is equally important that the radiologist has sufficient clinical background knowledge to understand the clinical significance of imaging findings. This book provides an overview of the findings obtained using different imaging techniques during the evaluation of head and neck neoplasms, both before and after therapy. All anatomic areas in the head and neck are covered, and the impact of imaging on patient management is discussed in detail. The authors are recognized experts in the field, and numerous high-quality images are included. This second edition provides information on the latest imaging developments in this area, including the application of PET-CT and diffusion-weighted magnetic resonance imaging."
