Summary
Imaging plays a vital role in diagnosing bone and soft-tissue sarcomas, with radiography, ultrasound, CT, and MRI being crucial. Advanced techniques and radiomics show future promise for sarcoma imaging.
Area of Science:
- Oncology
- Radiology
- Medical Imaging
Background:
- Advancements in imaging modalities enhance the detection and management of bone and soft-tissue sarcomas.
- Imaging is critical for surgical planning, assessing treatment response, and guiding biopsies.
Purpose of the Study:
- To review the current role of various imaging techniques in the evaluation of bone and soft-tissue sarcomas.
- To highlight the evolving applications and future potential of advanced imaging in sarcoma diagnosis and management.
Main Methods:
- A comprehensive literature search was conducted on PubMed.
- Keywords included "bone sarcoma," "soft tissue sarcoma," "imaging," and specific modalities like MRI, CT, and ultrasound.
- The search covered publications from 2005 to 2020.
Main Results:
- Radiography, ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI) are all essential for sarcoma evaluation.
- US is the initial choice for superficial soft-tissue tumors, while radiography remains crucial in diagnostic algorithms.
- CT's role is evolving with new techniques, and MRI provides noninvasive assessment of various structures.
Conclusions:
- Advanced MRI techniques are underutilized despite their potential benefits.
- PET/MRI and radiomics demonstrate significant promise for future sarcoma imaging.
- Machine learning may enhance personalized therapy selection for sarcoma patients.

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
