Extracardiac Tracer Uptake on Technetium-99m–Labeled Pyrophosphate Scintigraphy in Patients With Non-transthyretin Cardiac Amyloidosis

Koji Takahashi, Daisuke Sasaki, Nobuhisa Yamamura, Takaaki Iwamura et autres

Background: In patients with wild-type transthyretin (ATTRwt) amyloidosis, formerly known as senile systemic amyloidosis, ATTRwt deposition in soft tissues causes orthopedic diseases several years before cardiac manifestations. However, few studies have demonstrated extracardiac ATTRwt deposition before myocardial deposition through imaging modalities. This …

Iatrogenic intramuscular hematoma of the oblique muscles as a complication of technetium-99m-labeled pyrophosphate imaging-based computed tomography-guided core-needle biopsy in a patient with wild-type transthyretin cardiac amyloidosis

Koji Takahashi, Takaaki Iwamura, Yoshiyasu Hiratsuka, Daisuke Sasaki et autres

Technetium-99m-labeled pyrophosphate imaging-based computed tomography-guided core-needle biopsy of the internal oblique muscle with tracer uptake is a safe and sensitive extracardiac screening biopsy. It can provide histopathological confirmation of the deposition of amyloid transthyretin in patients with wild-type transthyretin cardiac amyloidosis. This …

A Gluteus Medius Muscle Biopsy to Confirm Amyloid Transthyretin Deposition in Wild-type Transthyretin Cardiac Amyloidosis: A Report of Two Cases

Koji Takahashi, Takaaki Iwamura, Yoshiyasu Hiratsuka, Daisuke Sasaki et autres

In patients with wild-type transthyretin cardiac amyloidosis (ATTRwt-CA), the uptake of the tracer on technetium-99m-labeled pyrophosphate (99mTc-PYP) scintigraphy, which indicates amyloid transthyretin (ATTR) per se, is often observed in skeletal muscles, such as the abdominal oblique and gluteal muscles. Among extracardiac biopsies …

Technetium-99m-pyrophosphate imaging-based computed tomography-guided core-needle biopsy of internal oblique muscle in wild-type transthyretin cardiac amyloidosis

Koji Takahashi, Yoshiyasu Hiratsuka, Takaaki Iwamura, Daisuke Sasaki et autres

Background Technetium-99m-pyrophosphate (99mTc-PYP) uptake in the internal oblique muscle (IOM), which is often observed in patients with wild-type transthyretin cardiac amyloidosis (ATTR-CA), indicates amyloid transthyretin (ATTR) deposition.Objective This study aimed to assess the safety and efficacy of 99mTc-PYP imaging-based computed tomography (CT)-guided …

99mTc-Pyrophosphate Scintigraphy Can Image Tracer Uptake in Skeletal Trunk Muscles of Transthyretin Cardiac Amyloidosis

Koji Takahashi, Yoshiyasu Hiratsuka, Daisuke Sasaki, Tomoki Sakaue et autres

PURPOSE: 99mTc-pyrophosphate (99mTc-PYP) uptake in the skeletal muscles is minimal in patients with transthyretin cardiac amyloidosis (ATTR-CA) when assessed qualitatively and quantitatively. We previously demonstrated moderate- to high-grade 99mTc-PYP uptake in the subcutaneous abdominal fat of some patients with ATTR-CA and showed …
