Pectoralis muscle atrophy/hypertrophy

Pectoralis muscle atrophy/hypertrophy refers to changes in the size of the pectoralis muscles, which are the major muscles located at the chest.

Atrophy involves the decrease in muscle mass, often due to disuse, nerve injury, or underlying medical conditions.

Hypertrophy, on the other hand, is the increase in muscle size, usually a result of strength training and adaptive muscle growth.

This condition affects the musculoskeletal system, specifically the bony and muscular structures of the chest.

Atrophy can lead to muscle weakness, asymmetry, and functional impairment, while hypertrophy might lead to enhanced muscle strength and bulk.

However, excessive hypertrophy could potentially cause issues such as muscle imbalances and restricted range of motion.

Detection of these changes can be effectively performed using imaging studies such as MRI or CT scans, which provide detailed views of soft tissue and muscle architecture.

These scans fall under the 'Torso' category and, thus, are included in 'Head & Torso' and 'Whole Body' scans as well.

Understanding pectoralis muscle atrophy/hypertrophy is crucial for developing appropriate rehabilitation or training programs, ensuring muscle balance, and preventing potential complications related to muscle size changes.
