Comparative Study
Added value of SPECT/spiral CT versus SPECT or CT alone in diagnosing solitary skeletal lesions.
The aim of this study was to investigate the added value of SPECT/spiral CT versus SPECT or CT alone in the differential diagnosis of solitary skeletal lesions. ⋯ Compared with SPECT or imaging alone, SPECT/spiral CT imaging was more accurate and valuable in the differential diagnosis of solitary skeletal lesions and resulted in significantly fewer equivocal findings.

Evaluate the diagnostic accuracy of 68Ga-labeled HBED-CC-PSMA-PET/MRI for detection of recurrent PCa in comparison to PET/CT. ⋯ 68Ga-HBED-CC-PSMA-PET/MRI was found to be superior as compared to 68Ga-HBED-CC-PSMA-PET/CT in the detection of PSMA-expressing prostate bed recurrences.

Comparative Study
Incremental value of 99mTc-HYNIC-TOC SPECT/CT over whole-body planar scintigraphy and SPECT in patients with neuroendocrine tumours.
The aim of this study was to evaluate the additional value of 99mTc-HYNIC-TOC SPECT/CT over planar whole-body (WB) scintigraphy and SPECT alone in the detection and accurate localisation of neuroendocrine tumour (NET) lesions. ⋯ The sensitivity and diagnostic accuracy of SPECT/CT in the evaluation of NET lesions outperforms planar WB imaging or SPECT alone.

To assess whether clinical prostate cancer (PCA) related factors and therapy status can predict the degree of tracer uptake on [68Ga]PSMA-HBED-CC PET/CT. ⋯ Signifikant positive Korrelationen zwischen Läsionsgröße und SUVmax wurden in pelvinen Lymphknotenmetastasen > 5 -≤15 mm (Spearmans rho = 0.502, p = 0.002), extrapelvinen Lymphknotenmetastasen5 mm (rho = 0.314, p = 0.033) und > 5 -≤15 mm (rho = 0.614, p < 0.001) gefunden. Für jede anatomische Lokalisation wurde ein höherer Wert SUVmax innerhalb der größten Kategorie verglichen zu mittleren und kleinsten Kategorie gefunden.

Multicenter Study
Rate of elimination of radioiodine-avid lymph node metastases of differentiated thyroid carcinoma by postsurgical radioiodine ablation. A bicentric study.
SPECT/CT detects radioiodine-positive cervical lymph node metastases (LNMs) of differentiated thyroid carcinoma (DTC) at the time of postsurgical radioablation (RA). Preliminary evidence indicates that the majority of LNMs are successfully treated by RA. The aim of this study was to confirm this evidence in a bicentric setting and to evaluate whether size is a predictor for successful elimination.
