Diagnostic Value of Bone SPECT/CT in Patients with Suspected Osteomyelitis.

Objectives: The aim of our retrospective study was to evaluate the contribution of single photon emission computed tomography/computed tomography (SPECT/CT) to three phase bone scintigraphy/SPECT for the assessment of osteomyelitis (OM) and patient’s management.

Methods: Eighty-five patients who were suspected as having OM were included in this study. Tc-99m MDP three phase bone scintigraphy and SPECT/CT were performed to the region of suspected OM.

A Case of Hypertrophic Pulmonary Osteoarthropathy in Both Upper and Lower Extremities: A Rare Involvement.

Hypertrophic pulmonary osteoarthropathy (HPOA) is a paraneoplastic manifestation of gastric and, more frequently, lung carcinomas. It is characterized by extremity pain, clubbing, arthritis and periostitis of the long bones. Periostitis is the hallmark of HPOA and can be revealed with bone scintigraphy.

A Family with Von Hippel-Lindau Syndrome: The Findings of Indium-111 Somatostatin Receptor Scintigraphy, Iodine-123 Metaiodobenzylguanidine Scintigraphy and Single Photon Emission Computerized Tomography.

Von Hippel-Lindau syndrome (VHLS) is an autosomal dominant hereditary familial disorder characterized by development of malignant and benign neoplasms. Differential diagnosis of the adrenal and pancreatic masses are difficult in patients with VHLS. Iodine-123 metaiodobenzylguanidine (I-123 MIBG) and indium-111 somatostatin receptor scintigraphies (In-111 SRS) have important roles in the differential diagnosis of adrenal and pancreatic masses in those patients.

The role of bone SPECT/CT in the evaluation of painful joint prostheses.

Objective: In this study, we aimed to evaluate the contribution of single-photon emission computerized tomography/computed tomography (SPECT/CT) to three-phase planar bone scintigraphy/SPECT in the assessment of aseptic and septic prosthesis loosening in patients with painful hip and knee prostheses.

Methods: Fifty patients who had undergone arthroplasties (20 hips and 30 knees) and were suspected to have complications and had undergone revision surgery were included in this study. Technetium-99m methylene diphosphonate three-phase bone scintigraphy and SPECT/CT were performed at the region of prostheses in all patients.

Painful Chest Wall Swellings: Tietze Syndrome or Chest Wall Tumor?

Background:  Tietze syndrome (TS) is an inflammatory condition characterized by chest pain and swelling of costochondral junction. Primary chest wall tumors may mimic TS. In this article, we report our experience of approximately 121 patients initially diagnosed as TS and determined chest wall tumor in some cases at the follow-up.

The effect of the excisional biopsy in the detection of the sentinel lymph node by lymphoscintigraphy and intraoperative gamma probe in breast cancer.

Objective: Sentinel lymph node (SLN) scintigraphy is used widespread in breast cancer, but the effect of the radionuclide agent, injection technique, the method of biopsy, tumor localization, breast size remain controversial. We examined the effects of the excisional biopsy in the rate of the SLN identification with lymphoscintigraphy (LS) and intraoperative gamma probe (IGP).

Material And Methods: One hundred patients (age range: 28-79 yr) with breast cancer were included in the study.

Nephron-sparing surgery: the effect of surface cooling and temporary renal artery occlusion on renal function.

Aims: To evaluate whether transient renal artery clamping and external renal hypothermia cause any detrimental effect on the remaining renal parenchyma after nephron-sparing surgery with the use of (99m)Tc-DMSA-SPECT.

Methods: Twenty-eight patients with a unilateral renal mass but a normal contralateral kidney underwent nephron-sparing surgery. Serum biochemistry, 24-hour urinary creatinine clearance and absolute uptakes of the injected dose (%ID) of both kidneys as measured by renal (99m)Tc-DMSA-SPECT were compared preoperatively and in the 3rd postoperative month.

Resolution of cortical lesions on serial renal scans in children with acute pyelonephritis.

Background: The ideal time for distinguishing a renal scar from acute inflammatory lesions by renal DMSA scintigraphy remains controversial.

Objective: To determine the time needed for resolution of lesions after acute pyelonephritis.

Materials And Methods: A total of 105 children with acute pyelonephritis underwent renal sonography, voiding cystourethrography and baseline DMSA scintigraphy.

Subclinical neurological involvement in Behçet's disease.

Context: Behçet's disease (BD) is a multisystem inflammatory disorder with unknown etiology characterized by recurrent oral and genital aphthous ulcers and uveitis. Behçet's disease can affect the central nervous system.

Aims: We aimed to investigate subclinical neurological involvement in patients who were suffering from BD and who had no neurological symptoms.

Brain perfusion abnormalities in chronic obstructive pulmonary disease: comparison with cognitive impairment.

Objectives: To clarify cerebral perfusion distribution and cognitive functions in patients with chronic obstructive pulmonary disease (COPD) according to the hypoxia levels and to assess if there is a relationship between cognitive impairment and cerebral perfusion index.

Patients And Methods: Eight patients with stable hypoxemic COPD (HC), 10 patients with stable nonhypoxemic COPD (NHC), and 10 age-matched healthy volunteers participated in the study. All subjects underwent a complete neuropsychological assessment with the mental deterioration battery (MDB), Wechsler memory scale-revised (WMS-R), color trail test (CCT), and grooved pegboard test (GPT).

The frequency of sacroileitis and ankylosing spondylitis in inflammatory bowel disease and HLA-B27 association.

Background/aims: The aim of this study was to investigate the frequency of sacroileitis and ankylosing spondylitis in inflammatory bowel disease and the relationship between disease activity, joint symptoms and HLA-B27 antigen positivity.

Methods: Sacroiliac joint radiography and three phase bone scanning of 33 ulcerative colitis patients (17 active and 16 in remission) and 29 Crohn's disease patients (15 active and 14 in remission) was performed. HLA-B27 was determined in all patients and 60 control subjects.

Hemodynamic evaluation of varicocele: the role of scrotal scintigraphy and Doppler ultrasonography in the prediction of postoperative seminal improvement.

Aim: The aim of this study was to evaluate the hemodynamics of varicocele using Doppler ultrasonography and scrotal scintigraphy, and to compare the value of these two methods in the prediction of seminal improvement after varicocelectomy.

Materials And Methods: A total of 40 men with left sided varicocele presented for surgery because of infertility of at least one year in duration. Preoperative and postoperative sperm counts and per cent motility were obtained.

Differential renal function in the prediction of recovery in adult obstructed kidneys after pyeloplasty.

Aim: Pyeloplasty is a widely accepted method for the treatment of ureteropelvic junction obstruction (UPJO). Surgery has long been thought to affect postoperative renal function.
