The overwhelming majority of these represent benign hyperplastic nodules or adenomas. Approximately 5% of nodules are malignant, with papillary carcinoma representing approximately 75% to 80% of primary thyroid malignancies. Although many sonographic features have been studied as a means of distinguishing benign from malignant nodules, ultrasound- guided fine-needle aspiration with cytologic evaluation remains a mainstay in the management of palpable and incidentally detected nodules. This article reviews the current techniques for sonographic evaluation of the thyroid and the imaging features of the various types of thyroid nodules.Ultrasound of Thyroid NodulesTerry S.

The sonographic appearance of lymph node metastases may vary from subtle alterations in echogenicity or vascular patterns to more obvious findings of calcifications and cystic changes within an affected node. Identification of metastatic disease to lateral cervical lymph nodes by sonography may affect the extent of surgical resection at the time of diagnosis. In patients who have had thyroidectomy for cancer, sonographic evaluation has proved to be the most sensitive imaging technique to detect thyroid cancer recurrence in the neck.Sonographic Imaging of Cervical Lymph Nodes in Patients with Thyroid CancerJill E.

It also contains an indepth discussion of the use and interpretation of color Doppler and power Doppler imaging, techniques that do not seem to be understood or used fully in daily practice.Diagnostic Breast Ultrasound: Current Status and Future DirectionsWei Yang, Peter J.

This article reviews the role of echocardiography (M-mode, two-dimensional, spectral, and tissue Doppler) for qualitative and quantitative hemodynamic assessment of the patient who has heart failure. It highlights the echocardiographic parameters that have the most diagnostic and/or prognostic relevance for patients who have advanced heart failure. The importance of right heart failure and heart failure with preserved ejection fraction is increasingly recognized, and therefore the echocardiographic evaluation of these conditions is emphasized also.The Role of Echocardiography in Hemodynamic Assessment in Heart FailureJacob Abraham, Theodore P. Abraham10.1016/j.cult.2009.04.002Ultrasound Clinics 4, 2 (2009)2009-04-01Ultrasound Clinics2009-04-0142S1556-858X(09)X0003-4149166http://www.ultrasound.theclinics.com/article/PIIS1556858X09000115/abstract?rss=yesEchocardiography serves an extremely important role in the diagnosis and management of patients with heart failure. The various stages of structural and functional changes that constitute progressive left ventricle remodeling have all been characterized by two-dimensional echocardiography. In addition, echocardiography has defined the transition from compensated hypertrophy to left ventricle dilatation and progression to end-stage heart failure. Echocardiography has also played an important role in clinical heart failure trials of b-adrenergic blocking agents and angiotensin-converting enzyme inhibitors and angiotensin receptor blockers and demonstrated their efficacy in heart failure.Assessment of Left Ventricular Systolic Function by EchocardiographyMartin G.

When sonographic findings are equivocal or nondiagnostic, particularly in evaluating the central deep veins, MR venography or catheter venography correlation may be helpful. Ultrasound provides an accurate, rapid, low-cost, portable, noninvasive method for screening, mapping, and surveillance of the upper extremity venous system.Upper Extremity Venous Doppler UltrasoundTherese M.

This article addresses the role of duplex ultrasonography and color Doppler ultrasonography in today's clinical practice for the evaluation of patients suspected of harboring a thrombus in their lower extremity veins. It reviews the clinical presentation and differential diagnoses, technique, and diagnostic criteria for acute and chronic DVT. In addition, it addresses the sonographic evaluation of venous insufficiency.Ultrasound Evaluation of the Lower Extremity VeinsUlrike M. Hamper, M. Robert DeJong, Leslie M.

Core concepts that are common to most ultrasoundguided procedures are reviewed, including an in-depth discussion regarding the use of injectable corticosteroids. Various aspects of intra-articular, intratendinous, bursal, and ganglion cyst intervention are discussed and promising advances in the treatment of chronic tendon disorders are presented.Musculoskeletal Ultrasound Intervention: Principles and AdvancesLuck J.

Its advantages include its capacity to allow evaluation during dynamic maneuvers, imaging of patients who cannot undergo MR imaging, and real-time evaluation of the symptomatic site. It can also reveal abnormalities that are not apparent during static imaging. This article makes the case that radiologists should continue to be experts in all aspects of musculoskeletal imaging, including ultrasound or the business will be taken over by other specialties. If musculoskeletal ultrasound is lost, additional modalities such as MR imaging may be lost as well. Radiologists, with their expertise and years of training, are uniquely suited to apply this versatile modality to foot and ankle pathology.Ultrasound of the Hindfoot and MidfootDavid P.
