Karimzadeh A, Burkhardt A, Klutmann S, Apostolova I, Buchert R
Clin Nucl Med . 2025 Feb; PMID: 39894991
Multiple-pinhole collimators provide considerable improvement of SPECT system count sensitivity. This case report suggests that SPECT with brain-specific multiple-pinhole collimators enables cerebral perfusion imaging with diagnostic quality by an early...

Karimzadeh A, Hansen K, Hasa E, Haller B, Heck M, Tauber R, et al.
Eur J Nucl Med Mol Imaging . 2025 Jan; PMID: 39847077
Purpose: This retrospective analysis evaluates baseline F-flotufolastat positron emission tomography (PET) parameters as prognostic parameters for treatment response and outcome in patients with metastatic castration-resistant prostate cancer (mCRPC) undergoing treatment...

Karimzadeh A, Lehnert W, Koehler D, Shenas F, Kisters A, Apostolova I, et al.
Rofo . 2025 Jan; PMID: 39842443
Theranostics in nuclear oncology combines diagnostic and therapeutic procedures using radiotracers to target tumor cells. Prostate-specific membrane antigen (PSMA) is a key target in metastatic prostate cancer, and the radioligand...

Apostolova I, Hellwig S, Karimzadeh A, Klutmann S, Meyer P, Buchert R
Eur J Nucl Med Mol Imaging . 2024 Nov; 52(4):1549-1555. PMID: 39614909
Purpose: This study examined the impact of venlafaxine and bupropion on the detection of nigrostriatal degeneration by dopamine transporter (DAT)-SPECT. Methods: 43 patients (70.7 ± 8.6y, 44% female) with [I]FP-CIT-SPECT...

Karimzadeh A, Hecker C, Heck M, Tauber R, DAlessandria C, Weber W, et al.
EJNMMI Res . 2024 Oct; 14(1):94. PMID: 39402311
Background: The optimal regimen for Lu-labeled prostate-specific membrane antigen-targeted radioligand therapy, including treatment intervals, remains under study, with evidence suggesting shorter intervals could benefit patients with high disease volume and...

Baradaran-Salimi K, Karimzadeh A, Voges B, Apostolova I, Sauvigny T, Simova O, et al.
EJNMMI Res . 2024 Sep; 14(1):83. PMID: 39264384
Background: Ictal brain perfusion SPECT provides higher sensitivity for the identification of the epileptic seizure onset zone (SOZ) than interictal SPECT. However, ictal SPECT is demanding due to the unpredictable...

Karimzadeh A, Schatz L, Sauer M, Apostolova I, Buchert R, Klutmann S, et al.
EJNMMI Phys . 2024 Jul; 11(1):63. PMID: 39017988
Background: Internal dosimetry in individual patients is essential for safe and effective radioligand therapy. Multiple time point imaging for accurate dosimetry is time consuming and hence can be demanding for...

EJNMMI Res . 2024 Apr; 14(1):40. PMID: 38630381
Background: The aim of this study was to assess the impact of the post-injection electrical seizure duration on the identification of the seizure onset zone (SOZ) in ictal brain perfusion...

Ristow I, Well L, Wiese N, Warncke M, Tintelnot J, Karimzadeh A, et al.
Cancers (Basel) . 2024 Mar; 16(5). PMID: 38473353
Objectives: To compare the feasibility and reliability of manual versus software-assisted assessments of computed tomography scans according to iRECIST in patients undergoing immune-based cancer treatment. Methods: Computed tomography scans of...
