Of eight patients with pulmonary arterial hypertension, final diagnosis established by autopsy or angiography, four had primary hypertension and from thromboembolism. The perfusion lung scan was distinctly different in the two groups. associated nonsegmental, patchy defects of perfusion, while thromboembolic hypertensives it characterized segmental and/or lobar without subsegmental defects. is a valuable, noninvasive study evaluation patient undetermined cause exclusion occult large-vessel

Fecal stasis in an ileal reservoir may lead to overgrowth of bacteria and changes mucosal morphology that are future concern. Moreover, improper evacuation increased stool frequency reduced continence. The aims this study were: compare the functional results two types reservoirs constructed with ileoanal anastomosis, their emptying a normal rectum as assessed by radionuclide enema, correlate emptying. were made (J) or three (S) limbs terminal ileum. Thirty-three patients (16 J-pouch 17...

Myeloid sarcoma is a tumor formed by extramedullary accumulation of myeloblasts or immature myeloid cells. These tumors can develop in lymphoid organs, bone, skin, soft tissue, and other may precede occur concurrently with acute leukemia. This case 42-year-old man who presented 2-week history cough shortness breath on exertion. A computed tomography (CT) scan showed large mediastinal mass pericardial effusion. An F-18 fluorodeoxyglucose positron emission tomography-CT intense (FDG) uptake...

This is a case of 52-year-old woman who underwent hysterectomy to treat large uterine perivascular epithelioid cell tumor. She was followed with serial F-18 FDG PET/CT scans due positive surgical margins and vascular invasion on pathology. Initial surveillance performed 6 months post surgery negative; however, second 12 showed an intensely FDG-avid recurrence in the pelvic site. The patient received local radiotherapy, 2 cycles taxol carboplatin, placed imatinib mesylate (Gleevec). A final...

Myositis ossificans is primarily a disorder of young adults, whereby an area muscle mass undergoes progressive ossification. The authors review case in which the patient's presentation was somewhat atypical, and where course disease unusually prolonged. Examination soft tissue lesion using Tc-99m diphosphonate bone scans helpful establishing diagnosis determining full extent process early its evolution.

A growing number of studies have demonstrated the usefulness FDG PET-CT in preoperative assessment soft tissue sarcomas. We report a case patient with known low-grade liposarcoma demonstrating only mild hypermetabolism on study. An incidental osseous lesion was found distal tibia same extremity during initial workup. This tibial significantly more intense study than primary sarcoma. Further investigation showed this to be an unexpected benign fibrous dysplasia. present as example discrepancy...

We assessed whether a combination of the fibrin tissue adhesive Tisseel® (human fibrinogen and thrombin) plus hemostatic matrix FloSeal® (bovine derived gelatin matrix/human could safely replace conventional deep medullary suture without compromising outcomes.Laparoscopic mid pole one-third partial nephrectomy was performed on right kidney 12 female pigs. The only difference between 2 groups 6 pigs each use in group instead running control 1. Renal scans angiograms were at baseline before...

This report of an 82-year-old man who presented with a 3-week history enlarging left axillary mass and mild fevers, highlights the usefulness both gallium-67 F-18 FDG PET/CT imaging in staging histiocytic sarcoma. While was superior determining extent disease, gallium can be used to help stage disease centers where is not available.

A 30-year-old woman was referred for an F-18 fluorodeoxyglucose (FDG) PET/CT to rule out lymphoma, and found have incidental FDG-avid right breast nodule that grew significantly in size FDG uptake on a subsequent scan, raising suspicion of growing malignancy. Histologic evaluation showed complex fibroadenoma with adenosis surrounding ductal hyperplasia. Although variable fibroadenomas has been described, distinction between simple not made the PET literature, even though higher propensity...

Angiomatoid fibrous histiocytoma is a very rare tumor that accounts for 0.3% of all soft-tissue tumors, and occurs predominantly in the extremities adolescents young adults. It has been classified by World Health Organization as uncertain differentiation with intermediate malignant potential, although recent evidence suggests myoid or myofibroblastic cell origin. Most examples behave an indolent manner regional recurrence rate 15% metastasis 1%. We present 29-year-old woman who was referred...

A 36-year-old woman presented with a 5-month history of growing left thigh mass, causing difficulty walking. Biopsy revealed malignant epithelioid hemangioendothelioma (EHE), and the patient was referred for staging F-18 FDG PET/CT that showed intense uptake in but no FDG-avid local lymph nodes or distant metastases. few reports have noted usefulness imaging EHEs lung, liver, bone marrow. This rare study highlights EHE soft tissues extremities.

Right ventricular infarction is not uncommon in patients with inferior myocardial infarcts. Phase and amplitude analysis of equilibrium gated cardiac blood pool studies useful documenting right damage complicating left infarction. In 15 37 acute infarction, extension the infarct was demonstrated by this approach, complementing findings avid imaging Tc-99m pyrophosphate (Tc-99m PYP).

Post-transplant lymphoproliferative disorder (PTLD) occurs in 1.2% of pediatric renal transplant patients, and is frequently Epstein-Barr Virus mediated. Hodgkin Lymphoma PTLD the rarest 4 types PTLDs recognized by World Health Organization, with an incidence <4% all patients. It has a distinct clinical course treatment from other PTLD. This case 16-year-old girl who had 2000 due to Moya disease. Her first F-18 FDG PET/CT done 2006 showed mildly FDG-avid mediastinal adenopathy...

Tc-99m red blood cell venography is a simple and sensitive technique for the diagnosis of deep vein thrombosis lower limb. The static high count pool images venous system leg are readily interpretable show good correlation with contrast venography. advantages limitations this in clinical setting discussed detail review.

A 64-year-old man with a history of smoking and asbestos exposure was referred for an F-18 FDG PET/CT, to evaluate multiple growing lung nodules that had been found incidentally on prior chest CTs. The PET/CT showed hypermetabolic in both the lungs, varying intensity uptake, raising suspicion multifocal malignancy. Wedge resections right were done remove 2 most nodules, histologic evaluation revealed pulmonary light heavy chain deposition disease. follow-up performed 1 year later another...

Clinical applicability of newly discovered reagents for molecular imaging is hampered by the lack translational models. As dog prostate cancer (DPC-1) model recapitulates in dogs natural history man, we tested feasibility single-photon emission computed tomography (SPECT)/CT this using an anti-prostate-specific membrane antigen (PSMA)/17G1 antibody as radiotracer.Immunoblots and immunohistochemistry (IHC) with 17G1 were performed on canine human cell lines tissues. Five DPC-1 tumors enrolled...
