Intraoperative Scintigraphy With Portable Gamma Camera for the Localization of Interaortocaval Paraganglioma
2021
A 15-year-old adolescent girl diagnosed of interaortocaval paraganglioma with a positive 123I-MIGB SPECT/CT and 1 unsuccessful prior surgery was operated on with the assistance of a handheld gamma camera. Once the lesion was located and removed, 2 images were taken, one of the surgical field (without 123I-MIGB uptake) and another of the tumor ex vivo (with high 123I-MIGB uptake), confirming that the lesion had been satisfactorily excised. This case highlights the use of a portable gamma camera as a useful tool to locate this rare tumor, with a SPECT/CT positive for 123I-MIGB and a difficult anatomical location suspected.
Lymphoscintigraphy for the diagnosis of extremity lymphedema: Current controversies regarding protocol, interpretation, and clinical application
2019
Appropriate diagnosis, staging and a further selection of the best treatment are fundamental for the management of patients with extremity lymphedema. Several clinical and imaging tools have been described for these purposes. Lymphoscintigraphy is still considered the gold standard imaging modality for diagnosing lymphedema. However, protocol variability and poor image resolution can make the interpretation challenging. Here, we reviewed technical aspects of lymphoscintigraphy, interpretation of the lymphoscintigraphy findings, staging, and its clinical application.
The optimal imaging test for diagnosis of acute pulmonary embolism: a second chance for lung scintigraphy?
2020
Ventilation–perfusion scintigraphy may continue to be the first-line diagnostic method for pulmonary embolism in institutions that can ensure its uninterrupted availability and the expertise in its interpretationhttps://bit.ly/2y3Dlhx
Ra223 in bone metastases with osteolytic activity
2018
Radium 223 dichloride (Ra223) is the only targeted alpha therapy able to extend survival in patients with bone metastases from prostate cancer. Mechanism of action and data currently available focused mainly on osteoblastic metastases from prostate cancer. In our institution, a patient with breast cancer affected by osteolytic metastases was treated with off-label use of Ra223. The evaluation of the deposit areas of Ra223 showed a perfect overlap with the regions of osteolysis previously detected by scintigraphy, indicating a possible therapeutic effect. This case report is the first document attesting Ra223 deposit in osteolytic metastases opening new opportunity of therapeutic development…
Active unilateral condylar hyperplasia : assessment of the usefulness of single photon emission computed tomography
2020
[Background] This study aims to evaluate whether the uptake difference by the condyles evaluated using single photon emission computed tomography (SPECT) examination is useful for predicting the activity of the feature and the advance of this pathology.
Abdominal splenosis and its differential diagnoses: What the radiologist needs to know
2021
Abstract Splenosis is a benign acquired condition characterized by the presence of heterotopic viable splenic tissue in other organs or within cavities such as peritoneum, retroperitoneum, or thorax after splenic trauma or surgery. Abdominal splenosis is often an incidental finding and computed tomography and magnetic resonance usually allow a confident diagnosis. The typical enhancement that parallels the spleen is a useful hallmark of splenosis. Splenic implants lack contrast uptake in the hepatobiliary phase and show high signal at high b-values on diffusion-weighted images. In some cases splenosis may mimic malignant and benign conditions in the peritoneum as well as in hollow and paren…
The significance of FNAC in diagnosing differentiated thyroid cancer and the discrepancy between theory and practice - a multi-centre study.
2020
After non-invasive diagnostic modalities high risk thyroid nodules are investigated with fine needle aspiration cytology in order to find the right surgical strategy for suspected malignancies. Despite the clear recommendation by the European and the American associations (ETA, ATA) its clinical value is doubted and its importance in clinical practice not fully clarified. A multicentric study of 119 patients with differentiated thyroid cancer operated on in 24 surgical departments was conducted. The aim was not only to evaluate the use of FNAC as a diagnostic tool, but also to investigate its diagnostic validity and compare it with that of other, non-invasive diagnostic methods. FNAC was u…
Nuclear Medicine Methods in Scrotal Imaging
2011
In patients with acute scrotal pain scrotal scintigraphy can be used to exclude torsion of the testicle, which presents with unilateral decrease in activity on the affected side.The role of nuclear medicine methods, however, faded in the last years after the introduction of high performance color Doppler ultrasound equipment. Lymphoscintigraphy can be used in patients with testicular cancer to demonstrate the lymphatic drainage pathway of the neoplasm. Several studies suggest that 18FDG-PET/CT might have a role in the staging germ cell tumors, in identification of recurrent/residual disease, to monitor the treatment response and during the follow-up. Other investigations, however, did not c…
Reduced regional systolic function evolved compacted segments in noncompaction
2010
Abstract In a recent report about noncompaction Nemes et al. reported that systolic left ventricular (LV) dysfunction assessed using the wall motion score during 2D echocardiography in noncompaction is not confined to noncompacted LV segments. These results confirmed some published reports of our group. Recently we analyzed a population of 238 patients affected by noncompaction, and demonstrated that the number of noncompacted segment is uncorrelated with the degree of systolic dysfunction. It is an attractive hypothesis that the systolic dysfunction could be depend on the fibrosis of the left ventricle, itself a consequence of microcirculatory dysfunction, which has been confirmed by repor…
Epitēlijķermenīšu scintigrāfiskā izmeklēšana ar planāro, SPECT un SPECT/CT metodi
2016
Bakalaura darba tēma ir “Epitēlijķermenīšu scintigrāfiskā izmeklēšana ar planāro, SPECT un SPECT/CT metodi”. Autors uzskata, ka tēmas aktualitāti nosaka scintigrāfijas izmeklējuma efektivitāte, epitēlijķemenīšu saslimšanas diagnostikā un tālākā ārstēšanā, piemēram, ķirurģiskā. Epitēlijķermenīšu scintigrāfija ir viena no visinformatīvākajām diagnostiskās radioloģijas metodēm, lai veiksmīgāk diagnosticētu dažādas patoloģijas, piemēram, primārs vai sekundārs hiperparatireoīdisms. Darba mērķis ir noskaidrot un salīdzināt planārās, SPECT un SPECT/CT metodes efektivitāti un to pielietošanu epitēlijķermenīšu saslimšanu diagnostikā un to precīzākas lokalizācijas noteikšanā. Darba uzdevumi ir noskai…
