توجه داشته باشید کتاب سونوگرافی تشخیصی: چاپ دوم (مجموعه دو جلدی) نسخه زبان اصلی می باشد و کتاب ترجمه شده به فارسی نمی باشد. وبسایت اینترنشنال لایبرری ارائه دهنده کتاب های زبان اصلی می باشد و هیچ گونه کتاب ترجمه شده یا نوشته شده به فارسی را ارائه نمی دهد.
این نسخه دوم که حاوی یک CD-ROM با کلیپ های ویدیویی ارزشمند برای پزشک است، استفاده از سونوگرافی تشخیصی را در تمام نواحی بدن بررسی می کند. این منبع با ارائه جداول و نمودارهای متعدد حاوی نکات کاربردی و توصیههای مفید، مشکلات خاصی را که ممکن است در هر ناحیه آناتومیکی بدن با آن مواجه شود فهرست میکند و روشهایی را برای تشخیص ناهنجاریهای مختلف سونوگرافی ارائه میدهد.
Containing a CD-ROM with valuable video clips for the medical practitioner, this Second Edition explores the utilization of diagnostic ultrasound in all regions of the body. Offering numerous tables and charts containing practical tips and useful recommendations, this source lists specific pitfalls that may be encountered in each anatomical area within the body and offers methods to distinguish among different sonographic abnormalities.
