X-ray is the first imaging modality typically used to evaluate bone tumors because it is widely available, cost-effective, and provides an initial assessment of bone structure. Radiographs can reveal abnormalities such as bone lesions, fractures, or changes in bone density that may indicate the presence of a tumor.

X-rays can help in identifying the size, location, and characteristics of the tumor, such as whether it is lytic (causing bone destruction) or sclerotic (causing bone formation). They also assist in distinguishing benign from malignant lesions based on specific radiographic features. After initial evaluation with X-ray, further imaging techniques, such as MRI or CT scans, may be employed for more detailed analysis or to evaluate surrounding soft tissues and structures.

The other imaging modalities mentioned can provide more detailed insights but are usually used after X-ray findings guide the need for further evaluation. MRI, for instance, is excellent for soft tissue evaluation and provides detailed images of the tumor's relationship with surrounding structures, but it is not the first line due to considerations like availability and time. Similarly, CT scans can provide detailed cross-sectional images but are generally utilized after initial findings on X-ray. Ultrasound is less commonly used for evaluating bone tumors, as it does not penetrate
