Clinical History:
Diagnostic CT was performed on this patient.
Findings:
Using Hawkeye as a bridge SPECT has been registered with external CT which demonstrate same type of image.
Final diagnosis:
Dedicated CT and the clinical symptoms confirmed the diagnosis of avascular necrosis in the femoral head.

Clinical History:
Man aged 72. Suspicion of cerebrovascular disease.
Findings:
SPECT shows a right fronto-parietal hypo-perfused area. Hawkeye CT shows an area of lower density and contrast. Fused dataset confirms co-registration of these areas.
Diagnosis:
A diagnostic CT was done and concluded to an area of more prominent cortical atrophy and excluded ischemic brain lesions.
Conclusion:
Hawkeye allows the detection of the morphological and functional brain abnormalities that may need additional diagnostic workout.

Clinical History:
Woman, 70. Stress pain and inflammation in the third finger left.
Findings:
SPECT shows increased focal activity probably at the distal inter-phalangeal joint. Hawkeye CT localizes this active area exactly on distal inter-phalangeal of the left medius.
Diagnosis:
Acute distal arthritis in the left medius. A fracture and tendinitis were excluded.

Clinical History:
Man aged 22. Lower back pain and decreased general condition.
Findings:
White bloodcell scintigraphy. SPECT shows medullary destruction at level of D12, L2, S1 and the left iliaca bone. Hawkeye CT shows heterogeneous bone structure, Paget-like, in the concerned area's although malignant bone formation can't be excluded. FDG-PET and bone scintigraphy are positive.
Diagnosis:
Aggressive Non Hodgkin Lymphoma.

Clinical History:
Man 87 with chronic obstructive lung disease and left hilar lung tumour. Sudden shortness of breath: quid lung embolism?
indings:
A major decreased perfusion in the left upper lobe and a heterogeneous perfusion elsewhere in the lungs.
Hawkeye CT shows the left hilar tumour with retro-obstructive fibrosis, obstructing the perfusion in the upper lobe.
Diagnosis:
No lung embolism. Loss of function in the left upper lobe due to an obstructing tumour. Obstructive lung disease.

Clinical History:
Woman, aged 52 with a 1 cm malignant tumour in the right breast. Tumorectomy and removal of the sentinel node is indicated.
Findings:
The sentinel node, discovered on planar and SPECT images is identified and exactly localised on the Hawkeye CT images.
The feature of combining the radioactivity with very precise anatomical information allows a very accurate surgical approach and a faster removal of the sentinel node.

Clinical History:
57 year old man. Right lower back pain.
Findings:
Increased uptake on the right side at the junction of the respective vertebral endplates of L4 and L5. Anatomical Hawkeye images reveals clearly erosive and degenerative lesions in the lower endplate of L4 and upper endplate of L5.
Diagnosis:
Discarthrosis L4-L5. A traumatic or malignant lesion was excluded.
Further radiological workout was avoided.

Clinical History:
Man, aged 33. Investigation for a hard subcutaneous nodule lateral in the right thigh.
Findings:
Very intense subcutaneous uptake. On Hawkeye CT, corresponding slices show a very dense or calcified lesion. Exact localisation is in between the biceps femoris and the vastus lateralis.
Diagnosis:
Calcified and inflammatory subcutaneous lesion most probably due to an old hematoma.

Clinical History:
Man, aged 54. Bone scan for staging a large malignant tumour of the larynx with left cervical metastatic lymph nodes.
Findings:
Physiological uptake of the bone tracer in a large left cervical metastatic lymph node.
A suspicious increased uptake in the upper dental left posterior arc. Hawkeye CT shows a dental implant. The high uptake is localized at the tip of a dental implant.
Diagnosis:
No bone metastasis and mechanical stress at the tip of the dental implant.

Clinical History:
42 year old patient with carcinoid diagnosed by biopsy of a liver lesion.
Findings:
Increase In-111 Somatostatin uptake detected in multiple bone lesions localized in the axial and peripheral sites with corresponding osteoblastic lesions on the CT part of the study. Multiple liver lesions detected on both SPECT and CT in the two liver lobes. Increased uptake was found in the left lung with a corresponding CT abnormality, consistent with lung involvement.
Diagnosis:
The findings on the In111-Somatostatin SPECT/CT study suggest metastatic carcinoid which is over expressing Somatostatin receptors.
