Summary
Single-photon emission computed tomography combined with computed tomography (SPECT-CT) precisely identifies skeletal pain sources in complex foot diseases. This advanced imaging technique offers valuable insights for diagnosing conditions like infections and tarsal coalition.
Area of Science:
- Nuclear Medicine
- Radiology
- Orthopedics
Background:
- SPECT-CT integrates the high resolution of CT with the high sensitivity of bone SPECT.
- It has gained significant clinical application in recent years.
- SPECT-CT is particularly useful in complex anatomical situations for pinpointing pain origins.
Purpose of the Study:
- To highlight the utility of SPECT-CT in diagnosing complex foot diseases.
- To emphasize its role in precisely defining the skeletal source of pain.
Main Methods:
- Utilizes SPECT-CT imaging.
- Combines bone SPECT (high sensitivity) with CT (high resolution).
Main Results:
- SPECT-CT accurately defines the skeletal area responsible for pain, especially in complex foot conditions.
- Demonstrates effectiveness in identifying pathologies in the foot.
Conclusions:
- Bone SPECT-CT provides valuable additional information for diagnosing conditions such as arthrodesis, infections, accessory bones (sesamoids), and tarsal coalition.
- Confirms the clinical utility of SPECT-CT in evaluating foot diseases.

01:11Pulse Assessment Sites
Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...
01:28Muscles of the Leg that Move the Foot and Toes
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.

01:10Bones of the Lower Limb: Tibia and Fibula
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
01:10Ankle Joint
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
01:31Diabetic Foot Ulcer
Definition A diabetic foot ulcer (DFU) is a chronic, non-healing wound that develops in individuals with diabetes. It typically occurs on pressure-bearing areas such as the heel, metatarsal heads, or hallux, and carries a high risk of infection and amputation.Pathophysiology • The development of DFUs can be explained by four interconnected mechanisms: neuropathy, ischemia, infection, and impaired wound healing. • Neuropathy is the most common factor. Sensory neuropathy reduces pain perception,...
01:16Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
