Avascular Necrosis of the Hips With Increased Activity on 68Ga-DOTATATE PET/CT

Avascular Necrosis of the Scaphoid Preiser Disease

No consensus regarding optimal treatment or etiology of Preiser disease exists. We described the epidemiology,classification and treatment characteristics of 18 patients with Preiser disease. Patients with changes related to previoustrauma, and without radiographs were excluded. Based on the radiographs at diagnosis, we classified 13 scaphoids asHerbert Lanzetta stage II, four...

Twins in spirit - episode I: comparative preclinical evaluation of [68Ga]DOTATATE and [68Ga]HA-DOTATATE

BACKGROUND Recently, an intra-patient comparison demonstrated that the somatostatin (sst) ligand [(68)Ga]HA-DOTATATE ([(68)Ga]DOTA-3-iodo-Tyr(3)-octreotate) provides PET images comparable to or superior to those obtained with [(68)Ga]DOTATATE. To provide a comprehensive basis for nevertheless observed slight differences in tracer biodistribution and dosimetry, the characteristics of [(68)Ga]HA-...

Avascular Necrosis of the Femoral Head: Are Any Genes Involved?

Avascular necrosis of the femoral head (ANFH) is a pathologic process that results from interruption of blood supply to the femur bone resulting in the death of bone cells and collapse of the femoral head. Nontraumatic ANFH continuesto be a significant challenge to orthopedic surgeons. While the exact mechanisms remain elusive, many new insights have emerged from research in the last decade tha...

Avascular Necrosis of the Capitate

Avascular necrosis of the capitate.

Avascular necrosis of the capitate is a rare entity. The most common reported etiology is trauma. We report a case of avascular necrosis of the capitate in a patient with chronic wrist pain that began after a single episode of remote trauma.
